We had a program, mcjl, that appeared to run on GTK 2.6, but the vendor said it needed GTK 2.8. To show what libraries the program uses, use ldd:

The pkg-config command will list the version of GTK:
root:~/newmcj# pkg-config --modversion gtk+-x11-2.0 2.6.1 root:~/newmcj# pkg-config --modversion gtk+-2.0 2.6.1 root:~/newmcj# |
