autogen.sh fails on RHEL 5.2

[Rodrigo Amestica <ramestica nrao edu>]

Hi,

I'm trying to get sawfish 1.3.4 installed from source in a RHEL 5.2 box. I have 
installed librep-0.17 and rep-gtk-0.18. For avoiding an .m4 error while 
installing librep I have renamed /usr/share (just temporarily during the librep 
compilation and installation) (rep-gtk requires patching for avoiding prototypes 
inconsistency).

For everything I'm using --prefix=~my-user-name/local

Now when I run autogen.sh in the sawfish directory I get the error shown below. 
Some reference in the web stated that for fixing this error one should install 
librep-dev, but this seems to be available only as an ubuntu package.

Is there something evidently wrong with my procedure?

thanks,
 Rodrigo
