libmcrypt (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/bin/libmcrypt-config from install of libmcrypt-devel-2.5.8-3.fc8 conflicts with file from package libmcrypt-devel-2.5.8-3.fc8 (Note that this is an automated bug filing.) It would be nice to have these bugs fixed by the beta of Fedora 9.
libmcrypt-2.5.8-4.fc7 has been pushed to the Fedora 7 stable repository. If problems still persist, please make note of it in this bug report.
