| gtkgl-2.0 gtkmm-2.4` -L`pkg-config --libs gtk+-2.0 gtkgl-2.0  
| gthread-2.0 gtkmm-2.4` testfunc.cc

Why are you using the -L in front of the `pkg-config ...` substitution
here:

  -L`pkg-config --libs gtk+-2.0 gtkgl-2.0 gthread-2.0 gtkmm-2.4`

Doesn't the "pkg-config --libs ..." command print the -L part of the
flags?
