The soname for the library has been set wrongly :-(

  soname_spec='${libname}${release}.so$major'
  library_names_spec='${libname}${release}.so$versuffix 
${libname}${release}.so$major ${libname}${release}.so $libname.so'

Hmm.  ISTR removing a `.' from the soname_spec some time ago.  I am
pretty sure this is fixed in HEAD...  I'll probably release 1.4d
shortly, since a lot of fixes have gone in since 1.4b.

Cheers,
        Gary.
