[Xymon] showgraph error

[Lynn Osburn]

When selecting any server parameter in the GUI that would result in a graph being shown, the graph does not render, and the apache error log shows:

/usr/lib/hpux32/dld.so: Unable to find library 'libz.so'.
Premature end of script headers: showgraph.sh, referer: http://rex07/xymon-cgi/svcstatus.sh?HOST=rxsap100&SERVICE=disk

Looks like there's still some niggling issue with zlib.  The file does exist, permissions ok to read it... just somehow not being found during the rendering phase.  (configure and compilations all ran without error)
#  ll /usr/local/lib/hpux32/libz*
-rw-r--r--   1 root       1307        300628 Mar 16  2007 /usr/local/lib/hpux32/libz.a
-rwxr-xr-x   1 root       1307        208148 Mar 16  2007 /usr/local/lib/hpux32/libz.so

Both the Xymon and Apache userids have the correct directory in the shared library search path SHLIB_PATH=/usr/local/lib:/usr/local/lib/hpux32:/usr/lib:/usr/local/rrdtool/lib
