Just tested with tkwidgets on MinGW.  It works fine.  It builds a
libtkwidgets.dll, and entry.dll links against it.  And it seems that
Windows automatically looks in the same folder for other dependent DLLs.
 And Mac OS X is working using @loader_path.

So we just need to figure out GNU/Linux and we have it.  tkwidgets
builds and links to libtkwidgets.so, and if I set LD_LIBRARY_PATH before
running Pd, it finds libtkwidgets.so.  Anyone have any ideas?
