configure: error: *** zlib missing

[Dustin Offutt]

OpenSSH v1.2.2p1
Solaris v2.6 Sun e450
gcc v2.8.1
Problem description: zlib has been installed, yet after using advice gleaned
from mail-list archives, got past what sounds like the normal
Solaris/OpenSSHv1.2.2p1 errors and am receiving a "configure: error: ***
zlib missing - please install first ***".

.../archive/zlib/1.1.3# make install
cp zlib.h zconf.h /usr/local/include
chmod 644 /usr/local/include/zlib.h /usr/local/include/zconf.h
cp libz.a /usr/local/lib
cd /usr/local/lib; chmod 755 libz.a
cd /usr/local/lib; if test -f libz.so.1.1.3; then \
  rm -f libz.so libz.so.1; \
  ln -s libz.so.1.1.3 libz.so; \
  ln -s libz.so.1.1.3 libz.so.1; \
  (ldconfig || true)  >/dev/null 2>&1; \
