[CentOS] Getting EXTERN.h, perl.h, etc

Hello:

I have a Fedora Core 11 system at home (Centos 5.2 at work).  I'd like 
to build vim with huge and perl.  This works under Centos, but fails at 
home: no EXTERN.h or perl.h (and, presumably, other things).  So: is 
there a yum package I should be downloading, and if so, which one?  
(both the home computer and the work computer are 64-bit systems)

Thank you,
Chip Campbell
