Hi Rob,

One more thought I had last night.

How about this. We have to change the library name anyway for different
languages. Why not make each separate version of guile a different
language? So you have libgwrap-guile-1.6 and libgwrap-guile-1.8 (I don't
want to think about 1.4 :). Then you have different pkg-config files, so
all you need to do in the configure.ac is

PKG_CHECK_MODULES(GWRAP, gwrap-guile-1.6 > $required_gwrap_version)

Or, or, or or or, you can go with not mangling the name and putting it
in a versioned dir, and have the pkg-config file (still with a mangled
name) pass -L directories as appropriate.

These sound like nice quick workable solutions. Messing with sonames
sounds painful, even if Correct.
