You need to write your perl program to instead, write shell commands to
stdout which accomplish what you want. Instead of saying
$ENV{GREGSVAR}='Hello';
say
print "export GREGSVAR=hello\n";
Assuming the perl program is call p and that you're running bash or some
other Bourne flavored shell:
eval $(p)
will do the job.
