One other thing about the Linux installations:
You should set LD_LIBRARY_PATH – so that the $GLADE_HOME/lib directory is found first.
If you don't, you may find that Glade picks up a different version of Qt libs.
In 4.3.37 for example, Glade was switch to Qt 4.8.4 from 4.8.2; it *may* work with the old libs but to be on the safe side check with
which should print a list of tha actual shared libs the application can find.
