[CentOS] mock rebuild of rsyslog dies

Hi All,

I'm not sure where I should ask this, so I'll try here and the Fedora list.

I'm using mock-0.6.13-1.el5_2.3 on a CentOS 5 box to rebuild i386 and x86_64 versions of rsyslog-3.21.10-2.fc10.src.rpm. But, the mock build always dies (for both archs) with the following error:

No Package Found for librelp-devel Cannot find build req librelp-devel. Exiting.

I can install that library on CentOS 5 outside of mock. I can even rebuild the SRPM outside of mock. So, I don't think there is a problem with the SRPM, but maybe there is. I don't know. :(

Does anyone know why librelp-devel wouldn't be found?

Regards,

Ranbir
