I don't have access to an HPUX machine so this help is going to be
minimal.

h_errno normally comes out of <netdb.h>, check if it's there and if
it's being included.  C library constants are a bit of a problem, as
folks seem to keep inventing different ways to make them thread-safe.
You may have to root around a bit and see what HPUX has done.

In the other one, there's no shared ncurses lib,  and the snipped line
is explicitly building a position-independent (PIC) shared object, but
is linking it with a static library which containts non-PIC code.
Since you presumably had to build ncurses yourself (a guess since it's
being found in /usr/local), you might try rebuilding ncurses.

I know this is buried in the bit that is handled with distutils and
while I like what distutils brings us, it's sometimes a little harder
to trace how these decisions were made before the compilation actually
kicks off.

:True, HP-UX's default compiler is only meant for compliling the kernel
:therefore  I installed  binutils v2.11.2,  gcc v3.01 and gmake v3.79.1 from
