You are running OSX 10.5 and the PMS binaries are built for OSX 10.6+
The last version of PMS that was compatible with 10.5 was 1.30.1
, if I'm not mistaking.
If you feel comfortable with code and compiling, you can build your own binaries on OSX 10.5 with the script "build-pms-binaries.sh
to a more recent version of OSX.
