Thanks for the tips!
I ended up adding this:
-I/var/www/html/bugztest/
to this:
#!/usr/bonsaitools/bin/perl
i.e.
!/usr/bonsaitools/bin/perl -w -I/var/www/html/bugztest/
in the perl files that I wanted to run with crontab.
A very cut and paste solution, not really sure exactly what its doing, but it worked!
Thanks again,
