I'm not the root user. Can I still install Razor Agents?

Yes. You need to specify PREFIX directory during install:

perl Makefile.pl PREFIX=/home/me/perl5

then, edit your .cshrc or .tcshrc

setenv PATH /home/me/perl5/bin:${PATH}
setenv PERL5LIB /home/me/perl5/lib
setenv MANPATH /home/me/perl5/man:${MANPATH}
