Hi
The RHEL 5 SRPM has BuildRequires: uuid-devel and enables it by default,
but there is no such package in RHEL 5.
Either the build, and the contrib package, must depend on EPEL in order
to get uuid-devel, or that needs to be disabled by default.
Presumably this works for current releases because EPEL is enabled on
the build machines (why?) and has uuid-devel installed.
