Comment (by kencu):

 The results of the {{{guile}}} 2.9.1 test suite on 10.5 Leopard PowerPC
 look quite encouraging:
 {{{
 Totals for this test run:
 passes:                 41258
 failures:               3
 unexpected passes:      0
 expected failures:      10
 unresolved test cases:  61
 untested test cases:    1
 unsupported test cases: 1
 errors:                 4
 }}}
 not quite perfect, but very very close. None of these gcc test suites ever
 seems to be 100% perfect, in my experience.

 I wonder if the main guile port is ripe to be updated to 2.9.1 as well,
 and what, if anything, would be broken by so doing...
