First, run the ./configure and make steps as a normal user and then su to root for the make install phase. I've run into installations where the environment (probably paths) needed to be that of a user. So 'su -' before make install would fail. It doesn't seem to be able to find directories that should be in the source. How did you extract the tarball? Are you located in the extracted directory or did you cd to one of the subdirectories?
Also, you may want to do a "make distclean" before retrying another "make".
Also, before I do a ./configure, I will read the README and INSTALL files and do a
./configure --help to find out if there are options that I need or want to use.
Lastly there version has an rpm package, you could try installing that way instead.
Sorry, that package may be for SuSE.
