OK, the problem was pretty easy to fix, I just have to add LTDL_LIBRARY_PATH=$PREFIX/lib:$LTDL_LIBRARY_PATH to the build environment. Interestingly, not having it was causing configure to think that srfi-1 was needed because of an lt_dlopen error, which caused the gnucash copies of the srfis to get added to the Guile path, which caused the truly ancient srfi-2 to get used.

lib/srfi/README says that the srfis are there to support older versions of Guile which don't include them; the minimum version of Guile that configure will accept is 1.6.0, which does distribute the srfis, so should the srfi directory and attendant configure checks go away?
