#229 abstractions are not found after make install

[Cyrille Henry]

when installing current git with make install, abstraction are copied with all of gem file in :
/usr/local/lib/pd/extra/Gem

This is correct, but after loading Gem, this abstractions are not found by pd.
according to -verbose option, pd search in /usr/local/lib/pd/extra but not in /usr/local/lib/pd/extra/Gem.
help file, that are on the same place can be found.

i think i found the problem:
If Gem does not detect Pd's s_stuff.h header during configure, it will build without support for auto-adding the search path.
d
commit [d8061a] will make the warnings more prominent, when something goes wrong.

the fix for the problem is to tell configure where to look for Pd's headers:

./configure --with-pd=/usr/include/pd
