I investigated shortly about those two:

Those failure are all because of an arbitrary choice which seem to depend on
sage version/achitecture/whatever... I'm making a patch to solve those.

I had a vast number of test failures on a machine which normally
behaves well, see here:
http://www.warwick.ac.uk/staff/J.E.Cremona/testlong.log

That includes 1378 "mysterious errors". the build produced no errors.
It's a 64-bit ubuntu machine.

Any ideas? Should I just scrap that build and do it again?

I only had those 2 failures (the finite_semigroups ones) on a machine
running 64-bit Ubuntu 9.10.

On a 32-bit ubuntu linux machine: build fine, the same 4 test
failures as on sage.math.
