I get the last version of OSBC on CVS and when I compile it in a linux CentOS 4.4 I have a Error...

When I compile the same version in a Slackware 12 the compiling is perfect...

What are the dependences of OSBC???

The error in CENTOS 4.4 is:

Are there some way to install the last version on CENTOS 4.4?

Thanks in advance...
