Hi Matthew,

Thanks for the helpful reply.  Evolution 2.8.2-5 was the latest version
I could find for SuSE 10.2 a few weeks ago.  I just did another search
on rpm.pbone.net and found evolution-2.10.1-8 here:

ftp://ftp.ntua.gr/pub/linux/opensuse/distribution/SL-OSS-factory/inst-source/suse/i586/

I will update the list if it helps shortly.
