Hmmmm... Which OS version are you building this on? If it's
5.2.1-RELEASE, I think that libc_r.so.5 should be replaced by
libpthread.so.N -- and one exceedingly annoying problem is that in a
dynamically linked program like Apache, parts of it can end up being
linked against libpthread, and other parts can be linked against
libc_r, which will cause the whole thing to crash.
One solution is to use /etc/libmap.conf to substiture libpthread for
libc_r during the dynamic link stage of program startup. See
libmap.conf(5). /etc/libmap.conf should contain something like:
libpthread.so.1 libpthread.so.1 # Everything uses 'libpthread'
libpthread.so libpthread.so
libc_r.so.5 libpthread.so.1 # Everything that uses 'libc_r'
libc_r.so libpthread.so # now uses 'libpthread'
Of course, the ultimate solution is to fix all of the ports and
recompile them so that they automatically link against the correct
threading library.
Cheers,
Matthew
