[gentoo-user] Is it possible to have perl-5 and perl-6 installed and in use concurrently?

[William Kenworthy]

Is it possible to have perl-5 and perl-6 installed and in use
concurrently?

This has come up because I am trying to upgrade mythtv using overlays
because gentoos mythtv builds are getting rather ancient - the drscream
(layman) overlay is requiring a perl 6 module, but the manual github
overlay which doesnt is January so is getting out of date anyway.

or can someone point me to a recent overlay thats regularly updated and
works(!)  Currently want to go from mythtv .23-gentoo to .24-fixes and
then .25 as its soon to be stable.

I had a look at the ebuild, it doesn't appear to be slotted.  So, it is 
most likely not possible to have both at the same time.  The relavant 
portion:

LICENSE="|| ( Artistic GPL-1 GPL-2 GPL-3 )"
SLOT="0"
KEYWORDS="~alpha ~amd64 ~arm ~hppa ~ia64 ~m68k ~mips ~ppc ~ppc64 ~s390 
~sh ~sparc ~x86 ~x86-fbsd"

All the ebuilds I looked at had the SLOT="0" which means no slots.

If I am wrong, someone post and correct me.

You can't have multiple versions of Perl installed in your system.

Its actually not "slotting" I am after - slots are a choice of setting
the system to one or the other (correct me if I am wrong) whereas I want
to use perl-5 for eveyting except this which wants perl-6.

One item is that the ebuild for perl5 is "dev-perl/libwww-perl" whereas
for perl 6 its "dev-perl/libwww-perl-6" which indicates co-existence
might be possible - but I dont want to break a system to prove it
doesnt :)

In order to have two versions of the same package on a system at the 
same time, the system has to be able to figure out which is which.  That 
is what Gentoo calls slots.  Here, I have python 2 and 3 installed.  I 
have the system set to python 2, with eselect, but some packages CAN use 
python 3 if it so chooses.  Maybe this link explains it better:

http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1#doc_chap5

Hope that helps.

You are wrong. slots is the mechanism whereby "different versions of a
single package can coexist on a system".  "Setting a choice" I assume
means your eselect-style choices.   For example, you can eselect a
pager, which has nothing do do with slots.  Or you can eselect the
system python, which does (indirectly) have to do with slots.  But
eselect and slots are not the same.

MythTV have their own overlay, which I've been using all year with no
problems, apart from one dodgy release that crashed the front end, but
that was months ago and easy to mask. Details here,

Thats the one (mythtv-0.24_p20110524.ebuild) that wants libwww-perl-6 -
how did you work that?  mythtv-0.24_p20110101 (from
https://github.com/drscream/mythtv-gentoo) is building for me att.

Also ran into a weird problem - everytime I tried to compile any version
of .24 it died with svn taking up 100% of one cpu - traced to having
PORTAGE_TMP on a btrfs filesystem! - moved it to a reisierfs one and its
steaming along fine! - odd ...

I didn't work anything, it pulled in libwww-perl-6, but I'm still using
perl-5.12.3-r1 and libperl-5.10.1

"libwww-perl-6" seems to refer to dev-perl/libwww-perl version 6.20.0,
as found in the main portage tree.

Ie, not libwww-perl for perl6 but rather version 6 of libww-perl for perl5.

Thanks for that - I saw the 6 and panicked :)
