[rt-users] When installing Request Tracker It says I'm missing dependencies such as DateTime that are actually installed

Good things to check are whether multiple perl installs have been done
(to avoid the problem of RT using /path/to/{cpan,perl} but the PATH
lists /some/other/{cpan,perl} first), and whether selinux is stabbing
you in the back yet again. I avoid the vendor perl on Redhat or sed
jobs of such, and install a custom perl to /opt/rt, and only use that
for RT, but care must be taken to only use that version. More elaborate
would be to only use /path/to/{cpan,perl}-5.18.1 and otherwise
specifically versioned command names, but that's a few extra steps
during the install of perl.

  ./Configure -des -Dprefix=/opt/rt4 && make test && make install
  /opt/rt4/bin/perl -MCPAN -e shell
    (then exit that)

  export PERL_MM_USE_DEFAULT=1
  export PATH=/opt/rt4/bin:$PATH
  env PERL=/opt/rt4/bin/perl ./configure \
   --enable-ssl-mailgate \
   --with-web-handler=fastcgi \
   --with-db-type=Pg \
   --with-web-user=apache --with-web-group=apache --with-rt-group=apache
  make fixdeps
 
  ...

  /opt/rt4/bin/cpan RT::Extension::...

Perlbrew would be another option, or building the custom perl into a
proper software depot, etc, depending on resources available.
