I can tell you why it doesn't work: You need either parentheses around the []
to make $1 work or replace $1 with $&.

Why it bombs is a separate issue that bears investigation.

Something to do with preference files. Runtimes use their own preference files
in preference (sorry :-) to the default MacPerl preference files. I don't
remember the exact algorithm, though.
