yum: Missing Dependency libpisock.so.8()(64bit)

[Richard Emberson]

I've got FC5 installed on a x86_64 system. Running 'yum -y update'
today resulted in a list of some 30 to 50 pacakges to be
updated and the error message:

--> Running transaction check
--> Processing Dependency: libpisock.so.8()(64bit) for package: evolution
--> Finished Dependency Resolution
Error: Missing Dependency: libpisock.so.8()(64bit) is needed by package 
evolution

On my system there is:

 > locate libpisock
/usr/lib64/libpisock.a
/usr/lib64/libpisock.so
/usr/lib64/libpisock.so.9
/usr/lib64/libpisock.so.9.0.0

so is this just a build problem in the yum update repositories?
