Hi All,
I am using Red Hat Enterprise Linux 5.5.
I installed rrdtool-1.0.50 successfully with steps(#./configure, #
make, # make install).
That is a relatively old version to install, even for RHEL5. I believe there are now packages in EPEL, but when there weren't, I provided one (1.2.x) in my repo (see below).
Similarly i installed pcre-8.12 successfully with steps(#./configure,
# make, # make install).
Why did you not 'yum install pcre-devel' ?
Finally once i try to install xymon-4.2.3
If you're only installing 4.2.3, why not use RPMs?
E.g., see http://staff.telkomsa.net/packages/Xymon.repo

Buchan
