If you get a chance, could you try again with current guile-3.0? Since the original report I downgraded guile-3.0 to 3.0.9 and then restored it to 3.0.10 along with the addtion of a number of patches destined for 3.0.11 that fixed various compilation problems in 3.0.10.
So I'm wondering if we may have addressed the original issue. Thanks -- Rob Browning rlb @defaultvalue.org and @debian.org GPG as of 2011-07-10 E6A9 DA3C C9FD 1FF8 C676 D2C4 C0F0 39E9 ED1B 597A GPG as of 2002-11-03 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4
