Wow. I'm stunned that Rapache shows up as a requirement.  I think the
other guys are right that  you should just use R from Epel, but if you
want to be a do-it-yourselfer, I would suggest he following.

DO NOT build R from source that way. DO get the SRPM file that is used
to build RPMS.  Then set your build directory in a file in your home
directory (.rpmmacros as I recall), then install the SRPM file, then
go read the SPEC file in the rpm tree. The SPEC file shows how the
thing is built, and you can rebuild in the command line like

$ rpmbuild -ba whatever.spec

This will give you an RPM that is exactly matching your system, same
as "configure ..  make" but more easily managed.  If you have trouble
getting started, I think I can double-check the instructions. I know
I've written them out before.

Here's another point.  The "default" configure statement for R's RPM
is much more elaborate than you think.  So trying it from scratch is
probably a big mistake.  If you look at the SPEC file, you will see
what I mean.

If you do succeed in building RPMS, it will be then easy for you to
take the RPM for Rapache and rebuild that for your system.  Or it will
be VERY OBVIOUS in the R spec file what you need to do to get rid of
the Rapache package requirement.  It sounds to me like a very
aggressive piece  of packaging, there, since most R installations will
never need it.

 Until you posted, I did not know that Rapache had been packaged in
Fedora, while running a RedHat system, I built my own.  It is a very
simple build, actually, it is just an apache module and a apache
config file.  Next time I have spare time, i will see how their
packaging differs from mine.

Or you can check and tell me. The installable is

Here's the SRPM, you could rebuild


Good luck. I hope this will be an exciting chance for you to join the
smart, clever group of RPM building linux users.  Advice I got years
ago: Never install anything with "make install" because it puts
unaccountable damage all over your file system, and if you do that,
set the prefix in the configure to be a unique, separate thing. Never
manually install into /usr.

And if something is worth building by hand, it is worth building in a
package so you can remove it!
