I'm sure the tree is up to date, and I've already done a complete
rebuild.

Aha...  Time for strace then, which includes:

open("/home/neil/SW/Guile/master/module/srfi/srfi-1.scm", O_RDONLY|O_LARGEFILE) = 10
open("/usr/local/lib/libguile-srfi-srfi-1-v-4.la", O_RDONLY) = 11
open("/usr/local/lib/libguile-srfi-srfi-1-v-4.so.4", O_RDONLY) = 11
open("/usr/local/lib/libguile.so.18", O_RDONLY) = 11

even though the real libguile was loaded well before then:

open("/home/neil/SW/Guile/master/libguile/.libs/libguile-2.0.so.18", O_RDONLY) = 3

So the problem appears to be srfi-1.scm picking up something old from
/usr/local/lib.  I'll dig deeper.

Thanks, I'll upgrade.

No problem, I think you've already provided enough clue for me to make
progress!
