From my test/development system:
- The supported kernels are called out in INSTALL in the tarball. I'm
  using linux-2.4.19-pre8 with the 2.4.19-pre8 futex patch, prior to 
  the release of NGPT 1.9.3. 
- I'm running NGPT 1.9.2.
- The distribution I use is Red Hat 7.2 with the later kernel
At this point I would use ngpt-1.9.3 with the latest kernel patches.
