this sounds very much like a bug that has been reported as
and which i have fixed in commit 7eb6c057 (11th september).
is your checkout recent enough?

once (after a successfull build) should be enough.
after doing "make install" you will have to use the path you installed
to (rather than the path where you built Gem).
$ mkdir -p ~/src/
$ cd ~/src
$ git clone https://github.com/umlaeute/Gem.git
$ cd Gem
$ ./autogen.sh && ./configure
$ make install DESTDIR=/tmp/Gem
$ cd ~
$ pd -path /tmp/Gem/usr/local/lib/pd/extra -lib Gem
so this boils down to:
"make install" will assemble everything to run Gem in a single
directory "somewhere else" (by default this is
/usr/local/lib/pd/extra), but is settable, e.g. with the DESTDIR variable.
it does not magically turn your build-tree into a usable (as in
"out-of-the-box") setup for running Gem.
if you have changed anything that involves recompilation, you have to
do "make install" again.

if the build fails for whatever reason (e.g. when building some plugin
you are not interested in anyhow), the "make instalL" will also fail,
and also some convenience symlinks that allow you to use the "-path
since the latter seems to work for you, i don't think that this is the
