[gentoo-user] mod_perl is hard to set up on gentoo; this even messes up vim

[Kevin O'Gorman]

I wanted mod_perl on my gentoo system.  It seems to be touchy about
thread safety.  Well that seemed reasonable, but it failed to emerge
(gentoo-speak for "install from source"), and left me without my
favorite editor (!!!): vim.

To handle thread-safety issues, I put this in /etc/package.use:
> # perl needs threads for mod_perl to work (or else mod_perl can't have threads)
> # Moreover vim cannot be built unless perl and libperl have the same use flags
> dev-lang/perl ithreads -ldap perlsuid doc
> sys-devel/libperl ithreads -ldap perlsuid doc
> www-apache/mod_perl ithreads -ldap doc

The result was failure.  I was not rebuilding vim, but it got killed
in the process anyway: it errors out on startup.
Moreover, I cannot re-emerge vim either, because it fails in about the
same way as mod_perl.
Both perl and libperl seem to build okay with the above lines in package-use.
My running kernel matches /usr/src/linux, so the headers should be good.
I'm looking for guidance from anyone who's using mod_perl with apache.
Here's the build log:

More info:
Even though the perl and libperl emerges seemed to go okay, they also
fail on startup, with pretty much the same complaint about this
Errno.pm file.  On looking at that file, I see that it says it's
auto-generated, and has this old 2.4 kernel string built-in.

Too bad there's no hint what I have to do to regenerate it.  I'll try
a few things, but I could really use some expert help at this point.

Oops: make that a 2.6.24 kernel string.

Where does this file come from?

That is from the file  /etc/portage/package.use, which is used by the
Gentoo package manager, "portage".  I've cross-posted this because it
appears to be a configuration issue, and requires some combination of
knowledge about Perl and Gentoo.

On my machines that generated file resides in /usr/lib/perl5/5.8.8/i686-linux
and belongs to the perl package itself.  I'd suggest deleting that file and
re-emerging perl to generate a new one.
