I agree it is a little annoying. For example, I currently don't have
SLEPc installed, but I don't want to be reminded about it every time
I compile something. Is there another way to handle this?

Perhaps at the end of the list of "Unable to find..." we could do
something like this:

Unable to find optional package: scotch
Unable to find optional package: gts
For instructions on how to enable these packages, see Foo.

where Foo could be README or scons/README or whatever?
