pmc2c2.pl fails on mac 10.2

[Klaas-Jan Stol]

I just got my OS 10.2 installation working today, and wanted to get a 
parrot on it, but when compiling, I get this error:

Badly balanced at classes/pmc2c2.pl line 316.
make: *** [classes/default.dump] Error 255
The source is a fresh checkout. I also tried the latest.tar.gz, but the 
problem stays.
On my Linux installation, I also did a fresh checkout, but there it works.

My macOS had perl version 5.6.0, so that should be allright. Also, 
running pmc2c2 without the --dump option *does* work.

What am I doing wrong?
(Btw, upgrading to 10.3 is not an option: it's an oldworld mac without 
USB (tried it, been there, done that))
