Compile of OpenSSH 3.7.1p2 failing - TRU64 5.1A

[Strickland, Trevor (Contractor)]

All,

I'm getting the following error message when trying to 'make' OpenSSH
3.7.1p2:

cc: Severe: compress.c, line 19: Cannot find file "zlib.h" specified in
#include directive. (noinclfilef)
#include "zlib.h"
-^
*** Exit 1
Stop.

What can I do to get this to compile correctly?

Thanks in advance,
Trevor Strickland
