Not really, *but* I've recently replaced Python by Guile in libgit2 tests. Maybe that broke something - especially if package-for-guile-2.0 somehow either provides both guile versions as native inputs or selects one incompatible with the "generate.scm" I wrote. Here, (ice-9 textual-ports) seems to be not found. Does it not exist in guile 2.0 ? (I wasn't aware we still used guile 2.0 for something...)
