I also got these warnings with 2.11.28.  This is the first time I've 
tried this trick on linux, so I'm not certain if this is a recent 
problem or not.  I'm considering compiling guile myself (Debian _still_ 
doesn't have 1.8.2, even in unstable!), but it would be nice if the 
EXTERNAL_BINARY trick worked for anybody else who wanted to help with 
the docs.

Cheers,
