Sure it does, just tell it what other prefixes you install stuff into, eg export PKG_CONFIG_PATH=$HOME/usr/lib/pkg-config > (In fact for me the use of PKG_CHECK_MODULES in configure.in > prevents me from installing on Debian at all, but that's possibly > another story). Broken debian pkg-config install ? Pretty much all libraries are switching to use of pkg-config these days precisely because it allows all of the million variations of per-library custom autoconf crack to be removed. Anything which removes use of m4 is a good idea :-) Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=| -- Libvir-list mailing list Libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
