[maemo-developers] Find out OS version in configure script

this is what I was looking for. I didn't know that a package called
maemo-version exists. Thanks a lot for the information :)

Just for reference, this is the solution with which I came up:

PKG_CHECK_EXISTS([hildon-1 >= 2.1.62], [AC_DEFINE([HILDON_HAS_APP_MENU],
[1], [Does hildon app menu exist])])

Cheers!
