[gentoo-user] Cannot emerge libgksu: lacks XML::Parser

[gentoo-user] Cannot emerge libgksu: lacks XML::Parser

[Kevin O'Gorman]

I've got portage's dev-perl/XML-Parser-2.36, but nevertheless several
packages have started to fail during emerge for lack of Perl's
XML::Parser.
Even the simple script fails to run under perl:
> #!/usr/bin/perl -w
>
> use XML::Parser;
>
> print "yes\n";

Do I have to get it from CPAN?

Consider libgksu; here's the end of the emerge output, where
XML::Parser is required by intltool:

checking for perl... /usr/bin/perl
checking for XML::Parser... configure: error: XML::Parser perl module
is required for intltool

Have you recently changed the "ithreads" USE flag on dev-lang/perl? If so, 
then you will need to remerge all ebuilds that installed files in 
/usr/lib*/perl5/vendor_perl/${PERL_VER}/${CHOST%%-*}-linux if "ithreads" was 
disabled, and /usr/lib*/perl5/vendor_perl/${PERL_VER}/${CHOST%%-*}-linux-
thread-multi if "ithreads" was enabled.

Also, if you have recently upgraded perl, the same provisions apply.

NOTE: In the above expansion, the following applies [sorry if you already 
know this]:

- "lib*" is lib on x86, lib64 on amd64
- ${PERL_VER} is your perl version, probably 5.8.8
- ${CHOST%%-*} is the part of the CHOST before the first "-":
  * on x86, it will be one of i486, i586, or i686
  * on amd64, it will be x86_64

If you aren't on x86 or amd64, I assume you can figure it out :).

This is helpful, as I do remember fooling with ithreads and not
getting it completely right.  I'm now emerging anything that has
'perl' in the name or category.

It has always baffled me, given this sensitivity, that all such
packages don't just declare that they use the 'ithreads' USE flag,
even if they don't explicitly.  Then my usual emerge --newuse would do
the Right Thing (TM).

The build scripts (makefile or whatever) of some packages will  
autodetect whether a feature is available. Thus they take advantage of  
another package's USE flag, without their own ebuild featuring it. I  
think this issue may be complicated by upstream decisions, thus  
complicating matters so that it may not be so easy for Gentoo  
developers to do the "right thing".

Why would  you get it from CPAN? Have you tried re-emerging the package?

It's surely saying that because the ebuild or makefile has a test  
script to see whether XML::Parser is present & working. Just as your  
`print "yes\n"` is failing so is the test run by the installation  
scripts, thus preventing install of libgksu.

It sounds like ABCD is on the right track with his suggestion  
regarding the "ithreads" USE flag. But in any case you might normally  
try re-emerging the package and running revdep-rebuild before calling  
us.

If I had this problem then - depending on how quick my machine was,  
how urgently I needed it fixed, and considering one might wait a few  
hours for a response here - I might well remerge everything with  
"perl" in the package name or category before becoming too flustered  
about this. You might well find that does the job.
