When compiling ganglia in linux we get the following error:
configure: error: apr-1-config binary not found in path
We are missing a package ganglia needs in order to compile. In particular the apr-util-devel package. To install this package you can use yum
yum install apr-util-devel
Now perform your configure again and this error should be resolved as long as ganglia can find the bin and libraries in your system.
