Yes.

Presuming you have:

/usr/include/plib-1.2.0

and

/usr/include/plib-1.3.1

and also:

/usr/lib/libplibssg.so.1.2.0
/usr/lib/libplibssg.so.1.3.1

then you could write a shell script:

plib-1.2:

  rm /usr/include/plib
  rm /usr/lib/libplib*.so
  ln -s /usr/include/plib-1.2.0 /usr/include/plib
  ln -s /usr/lib/plibssg.so /usr/lib/plibssg.so.1.2.0

and another:

plib-1.3:

  rm /usr/include/plib
  rm /usr/lib/libplib*.so
  ln -s /usr/include/plib-1.3.1 /usr/include/plib
  ln -s /usr/lib/plibssg.so /usr/lib/plibssg.so.1.3.1

(In reality, you'd have to link each of the plib*.so libraries - I only did
one - for brevity).

So far, every PLIB application that works with 1.2 has worked with
1.3.1 provided the 'configure.in' file was modified by adding:

   AC_CHECK_LIB(plibul,ulInit,,,)

...so you shouldn't have to resort to symlinks, etc.
