[PD] compiling external in linux

[Hans-Christoph Steiner]

Looks like you are using a very old Makefile. I highly recommend using
the Library Template.  Its well tested, easy to use, very
cross-platform, and even decently documented:

Its also very easy to then turn that library into a Debian or Gentoo
package.  And coming soon: RPMs.
