pptpclient and dependencies

[kgmorse at mpcu.com (Keith Morse)]

I'm going thru the documentation for pptpclient located on the
pptpclient.sourceforge.net site and am referencing the Fedora Core 3 how-to.

The docs refer to installing libglade and libxml and when I do so with a
"yum install libglade libxml"  no packages are found for installation. 
In looking at the installed packages I find libxml2.   Is libxml2
adequate for libxml or would it be neccessary to install libxml also?

Thanks for any help list members may be able to provide.
