Dependency problem with FC5

[Paul Smith]

Dear All

I am using 'yum update' to update my pptpconfig installation on a
Fedora Core 5 machine, but I am getting the following dependency
problem:

--> Running transaction check
--> Processing Dependency: xsu for package: pptpconfig
--> Finished Dependency Resolution
Error: Missing Dependency: xsu is needed by package pptpconfig

Any ideas?

Thanks in advance,

Paul
