ran into the problem of the mod_perl build dying without a trace and then did env USE="-ipv6" emerge mod_perl then it got farther .. but died when it did not find "apxs" installed. I could not find out anything about what apxs is .. but in the build messages I noticed that it was complaining that my PERL was build threaded. This is NOT correct as I ensured that i did not have "threads" in my USE var but in the output of the build: [33;01m*[0m PLEASE NOTE: If you want to compile perl-5.8 with [33;01m*[0m threading enabled , you must restart this emerge [33;01m*[0m with USE=threads emerge.... .. skip .. >>> Unpacking perl-5.8.0.tar.gz to /var/tmp/portage/perl-5.8.0-r12/work >>> Unpacking DB_File-1.806.tar.gz to /var/tmp/portage/perl-5.8.0-r12/work >>> Unpacking Safe-2.09.tar.gz to /var/tmp/portage/perl-5.8.0-r12/work [32;01m*[0m Applying perl-5.8.0-sockatmark-should-__THROW.patch... .. skip ..

umm .. i guess i should mention why this was a problem for me :-/ i want to run apache2 on this machine .. with PERL in its threaded version I have to build apache for threads also .. which I do not want to do. and some of the PERL things that I use break when PERL is threaded anyway. So .. how does it happen that PERL is ignoring the USE flag that is supposed to make it build as I want it to? at this moment I cannot move my web server to the new machine as i cannot install mod_perl .. thus the Critical rating on this bug
Posix threads (pthreads) is not the same as threading in perl. Your perl is not built with threading - says so in the output you pasted ;) That's the first two cents. Looking at the rest.
Another historic bug for the apache team to look at please ;-)
$ perl -V | grep thread This should show you that your perl is not threaded. ldd /usr/bin/perl ldd /usr/sbin/apache* These both show linking against pthreads, which is just what the mod_perl ebuild warns about. <quote> >>> Source unpacked. Will configure via APXS (apxs=/usr/sbin/apxs) ************* WARNING ************* Your Perl is linked with -lpthread, make sure that your httpd is built with LIBS=-lpthread ************* WARNING ************* </quote> Since the bug is related to threaded perl, it should probably be marked as invalid? apxs is probably the thing mentioned before the warning.
Closing because OP never made comment out after we made the distinction between perl threads and pthreads.
