Help with nn under Microport Sys V/AT 2.4?

[Manfred W. Prange]

I've just FTP'ed what I have been told is an unusually powerful
news reading package called nn, and have been trying to compile
and install it on my Microport V/AT 2.4 system. Scanning the
PROBLEMS file included with the package was this advice:

Can someone help me with this? I don't have an earlier version of
libcurses, I have only owned my copy of Sys V/AT for a few months.
I have looked for the m286 malloc on local sites, but have been
unable to find it. Also if anyone has had experience building/using
nn on Sys V/AT 2.4 please pass on any hints or tips you may have.
Thanks! -MWP  (fred at cetus)
