That entry also says that Fedora 8 can be used, which was the latest
Linux base port at the time the entry was made, and the skype port
Makefile says Fedora Core 6 __or later__ can be used. So presumably
later Linux base ports will also work: try the most recent Linux base
emulation port that is available for your platform.

The library's interface (API/ABI) hasn't changed, so the major version
number should remain the same. With the use of symbol versions, new
symbols, or different library symbols with the same interface can be
added, with the appropriate version number information, so that
binaries compiled against different versions of the symbols can all be
used with the library. So there is backwards-compatibility with
earlier versions of the library, but binaries that have been linked
with newer symbol versions during compilation will not link at
run-time against older versions of the library that don't have the new
versions of the symbols.

Yes, if you patch the run-time linker as PC-BSD does, or if you use
different environment variables or libmap.conf(5) to ensure the right
libraries are loaded when using different binaries. But this can get
messy -- try to use a new Linux base port for all of your ports first.
