That's the sort of conflict that is just impossible to resolve.
For your specific case, the path to the newly installed library
should go early, for other users it shouldn't (because they have
other, unrelated libraries in both the newly installed path and
some other path listed early).

Sorry, you can't have that sort of flexibility portably.
If you need other libraries from that path where the old,
unwanted one lives, make symlinks to them in some new directory.

Generally, if you want to have several versions of some library at the
same time, put them in distinct $prefix'es, apart from other libraries.
That helps to minimize such conflicts.

Cheers,
Ralf
