Might be because CentOS uses a different package manager... :-)

Did you try the steps provided in README (in the source directory of
the source distribution package you get from ruby-lang).

That must have been frustrating.

"man yum" or "yum --help" did not work?  yum has worked pretty well
for me so far so I never felt the need to install another package
manager.

Can you post the errors you got from "configure" or "make"?  On my
CentOS 5 (and also earlier on 4 IIRC) I did not have any issues
compiling.

Note that yum can tell you which package contains a specific file if
your error announces that a file (e.g. library) is missing (see
"whatprovides" in the man page).

But it might tell you that others do not have that problem and it's
probably not something about the distribution but your particular
installation.  This can be a crucial bit of information at times.
