It's kludgy for sure.

Having had to create such customized environments myself I sympathize,
but I would be happier if you would do roughly this yourself (which is
portable and easier to read than -I tricks IMHO):

$ cat bar.pl
#!/usr/bin/perl -Tw
# foo!

print "bar\n";

$ sed '1 s~^\(#!.*perl.*\)$~\1\nuse lib "/custom/perl/lib";~' *.pl
#!/usr/bin/perl -Tw
use lib "/custom/perl/lib";
# foo!

print "bar\n";

You should be able to work that expression into the transformation in
the Munin install procedure.

... It has been said that perl is the swiss army chainsaw of Unix.  Sed
is the swiss army knife at least.
