Okay, I downloaded the new RPMs for 4.1.0. I've been using the Fedora RPMS on CentOS, which seem to work perfectly. But, the FC4 RPMs need a little tweaking to get working, because the FC4 changes aren't in RH Enterprise (and CentOS) yet. I had to create links for /lib/libcrypto.so.5 and /lib/libssl.so.5 and install the RPM with --nodeps.
I'm not a big fan of doing this, but it seems to work. I like the RPMs, but should I be compiling the source instead of trying to force Fedora RPMs onto CentOS? I anyone else using RPMs with RH ES or CentOS?
