It what sense do you think 'it works fine'? How does a single
libtool version string get translated into the two possibly

I don't follow what you think is wrong. Libtool's versioning system
uses the CURRENT, AGE and REVISION system described in the libtool
documentation.
Does reading this thread help?
<http://thread.gmane.org/gmane.comp.gnu.libtool.patches/1348>
That link was helpful, but I think incorrect. In one of the messages
you have
Now lets release a new libfoo 4:0:2
Current system:
libfoo.dylib -> libfoo.2.2.0.dylib
libfoo.2.dylib -> libfoo.2.2.0.dylib
libfoo.2.2.0.dylib
install_name libfoo.2.dylib compatibility_version 5 current_version
5.0
Proposed :
libfoo.dylib -> libfoo.2.dylib
libfoo.2.dylib
same encoded information.
IMHO this should be:
Now lets release a new libfoo 4:15:2
libfoo.dylib -> libfoo.2.dylib (for the benefit of configure scripts
only)
libfoo.2.dylib
install_name libfoo.2.dylib compatibility_version 3.0.0
current_version 5.0.15
Possibly, the last line could equally be:
install_name libfoo.2.dylib compatibility_version 3.0.0
current_version 3.2.15
That would have the same effect on Darwin, if applied consistently.
If you set compatibility_version to 5, which is what seems to be
happening now, then something linked against the library built with
libtool version 3:10:1 will fail to link at runtime, even thought the
libtool version implies it is compatible.
I think your 2003 suggestion to eliminate libfoo.x.x.x.dylib is
correct. Creating that just results in unnecessary duplication.
