It worked! Thank you so much for your help!

depends on how you are going:
~> aclocal ~> autoconf ~> ./configure --with-pd=/path/to/my/pd ~> make ~> make install
or
~> make CONFIGUREFLAGS="--with-pd=/path/to/my/pd" ~> make install
note that the CONFIGUREFLAGS will have no effect if Make.config is already up-to-date, because then configure won't be executed. (if you are working on a "clean" copy of iemmatrix, it should work however)
furthermore, there is a PREFIX in the Makefile (Make.config)
