I noticed from strace (below) that, on my machine, ltdl tries to open
libguile-i18n-v-0.so from libguile/.libs, once it has failed with the
locations in LTDL_LIBRARY_PATH.  I'm guessing that this is a piece of
fallback "try to open .so in the same directory as the running
executable" logic, and that this logic wasn't present in some older
version of libtool.  (Although there is nothing in libtool's NEWS or
doc to support this.)

For tonight, therefore, I've committed the pre-inst-guile.in change,
and also some code in autogen.sh to display the versions of libtool et
al.  We'll see what that gives.
