Since "libgal" is exclusively for use by Evolution and GNUmeric, I'd double-check and see if it was actually part of your download, and you just need to copy it somwhere (for example, manually copy "libgal-2.0.so.3" to /usr/lib).
Otherwise, check out this link. Somebody else had the same problem, and they were able to find a copy of libgal on the web:
