In my sources, I use a PLplot global variable called build_tree that=20
says if the program being run was invoked inside the build tree(*); if=20
it was , then the path of the searched file in the build tree is used,=20
else the usual search path is used. This works fine for most drivers,=20
fonts and map files.
The tk driver is an exception, as it needs to find plserver, and tcl/tk=20
also needs its auto_path to be setup; in my sources this is also=20
working fine.=20
However,  I don't like the (tk) solution, as it is not general.
There is also the problem of having a global variable, build_tree, which=20
is ugly.

Joao

*-build_tree is set getting the current working dir, getcwd(), and=20
comparing with BUILD_TREE, which is setup at configure time and is=20
defined in config.h=20
