No, that is not correct.  The pfmon_3.0-1 packages includes
_both_ the 2.0 and 3.0 pfmon commands plus a wrapper that
determines what kernel is currently being run and execs the
proper pfmon.  Each of the pfmon commands was built using 
the proper version of libpfm.

The pfmon_3.0-1 packages depends on libpfm2_2.0-1 and
libpfm3_3.0-1 (but not the -dev packages).

There are:
   -- libpfm2 and libpfm2-dev packages.
   -- libpfm3 and libpfm3-dev packages.

Note that I chose to move the location of the header files
in the -dev packages so they wouldn't overwrite one another
(they used to both go in /usr/include/perfmon, but now go in
/usr/include/perfmon2 and /usr/include/perfmon3); the other
alternative was to completely rewrite them and merge them so
they had the proper API for the proper kernel version.  I may
yet do that, but it seemed more important to get the 3.0 stuff
out first.

Hmmm.  I must have missed a case in my install testing.
pfmon is set up to depend on libpfm2 and libpfm3.  libpfm2
was told to replace libpfm.  It looks like I forgot to tell
it to replace libpfm-dev, too.  Oops.  I'll rebuild and
upload later today.  If you remove libpfm and libpfm-dev
in the meantime, the install should proceed.  Sorry 'bout
that....
