The problem indicated by Bad : modifier in $ ($) is a problem with csh variable syntax. The colon has special significance if it follows a variable name. To isolate it, use {} around the variable name, much like in Perl. So 
setenv PERL5LIB ${SOURCE_ROOT}:$PERL5LIB

[download]
should do what you want.

However, the effort you are making to put (parts of) the original include path into $PERL5LIB is unnecessary. What you specify in $PERL5LIB is searched in addition to the original path. So, just 

setenv PERL5LIB $SOURCE_ROOT

[download]
should be enough.
