You are mixing apples and oranges, and in this case, it is particularly problematic.

SciPDL installs (afaik) against Apple provided perl which is in /usr/bin. I am 
going to assume that you already have PDL installed (perhaps you installed it yourself) 
under /usr/local/bin. Check the paths.

Correct the paths, and you should be ok.

If you want to use your own installed PDL, then, yes, that would be the way I would 
go about it. Here is what I did. I installed PDL using macports. The current version 
of PDL available on macports is 2.4.6. It gets installed in /opt/local/bin/ Then, 
against macports advise, I downloaded the PDL 2.4.10 source and manually compiled it.
Because /opt/local/bin is in my path before /usr/bin and /usr/local/bin, everything 
worked well for me.
