That's because from RT's position, mod_fcgid and mod_fastcgi present the 
identical fastcgi interface.

You should run the configure script in the RT4 source tree with 
"--with-web-handler=fastcgi" or no "--with-web-handler" argument at all, 
since fastcgi is the default.

Note that the configure script configures the RT source code for the 
ensuing build process, i.e. the 'make' commands. It DOES NOT configure 
Apache for you.

That's an indication that you do not have the UNIVERSAL::require Perl 
module installed in a proper location. The most likely cause of that on 
CentOS7 is using CPAN (particularly as a non-root user) to install Perl 
modules, as "make fixdeps" does. If done blindly, that is likely to 
result in a ~/perl/ directory with your CPAN-installed modules which 
won't be visible to RT.

You are better off enabling the EPEL repository and using yum to install 
the needed packages of Perl modules needed for RT. You can probably make 
"make fixdeps" do the right thing (once you've enabled the EPEL repo) by 
passing it a suitable alternative installation command in the 
RT_FIX_DEPS_CMD environment variable like this:

RT_FIX_DEPS_CMD='/bin/yum install -y perl-%s' make fixdeps

And of course, that must be run as root to be able to install the 
dependencies in the system-wide Perl library tree.
