Thank you for helping to resolve this issue. I bet the reason I did not see this failure on powerpc-darwin8-gcc-4.0.1 was because I happened to test it against an older glpk (< 4.29) way back then. I can at least patch the test case to work with glpk >= 4.29 (and require said version in our TestDepends), and move on from there. Is this test also present in ppl-0.11.x? Will it require the same adjustment?
