blitz (or one of its subpacakges) has multiarch conflicts when installed for both i386 and x86_64 in the Fedora development tree. For help in resolving them, see http://fedoraproject.org/wiki/PackagingDrafts/MultilibTricks. file /usr/include/blitz/gnu/bzconfig.h from install of blitz-devel-0.9-3.fc8 conflicts with file from package blitz-devel-0.9-3.fc8 file /usr/share/doc/blitz-devel-0.9/examples/Makefile from install of blitz-devel-0.9-3.fc8 conflicts with file from package blitz-devel-0.9-3.fc8 (Note that this is an automated bug filing.) It would be nice to have these bugs fixed by the beta of Fedora 9.
FWIW - I think a solution like that in http://fedoraproject.org/wiki/PackagingDrafts/MultilibTricks#myautoconf.h_files_with_a_size_in_them would be preferable to the current pkgconfig hack.
