[Xymon] Help installing rrd tool

Hi I am trying to install xymon on RHEL 4.9. When I tried to install rrdtool, I got the following error: "No acceptable C compiler found in $PATH". I do have path to gcc defined in the path. Not sure how to get past this error. Can someone help please?

Here is the output:

sudo ./configure checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking target system type... i686-pc-linux-gnu checking for gcc... no checking for cc... no checking for cl.exe... no configure: error: in /opt/iam/install/rrdtool-1.4.5': configure: error: no acceptable C compiler found in $PATH See config.log' for more details.

Thanks
