 dnl

+dnl --------------------------------------------------------
+dnl
+dnl General comments about PVM detection
+dnl
+dnl A typical installation has a hierarchy under PVM_ROOT that includes
+dnl PVM_ROOT/include/pvm3.h
+dnl PVM_ROOT/lib/pvmgetarch
+dnl PVM_ROOT/lib/<pvmarch>/libfpvm3.{a,so}
+dnl PVM_ROOT/lib/<pvmarch>/libgpvm3.{a,so}
+dnl PVM_ROOT/lib/<pvmarch>/libpvm3.{a,so}
+dnl
+dnl The setting for <pvmarch> is given by the output of the
+dnl PVM_ROOT/lib/pvmgetarch program.
+dnl
+dnl This typical installation has been seen on several different
+dnl operating systems and several different packaging systems.  It can
+dnl be considered the "normal" case.  In addition, the documentation
+dnl that comes with pvm3 says that the variable 
+dnl PVM_ROOT should be set in the users environment when using
+dnl pvm3 or compiling programs that use pvm3.
+dnl
+dnl --------------------------------------------------------
+dnl Variations that have been encountered "in the field" are:
+dnl
+dnl --------------------------------------------------------
+dnl header installed to /usr/include/pvm3.h but the rest of the install
+dnl to PVM_ROOT (where PVM_ROOT=/usr/share/pvm3 in one particular instance).
+dnl
+dnl This case can be dealt with by using the --with-pvm-includes option
+dnl --------------------------------------------------------
+dnl No shared libraries installed.  Only static libs.  This may cause
+dnl issues with linking on some systems.  This may have to wait for a real
+dnl world trial to see how it pans out.
+dnl --------------------------------------------------------
+dnl 
+dnl
+dnl The libraries installed by pvm3 are:
+dnl $PVM_ROOT/lib/$PVM_ARCH/libpvm3.a   -  C (base) library
+dnl $PVM_ROOT/lib/$PVM_ARCH/libfpvm3.a  -  Fortran wrapper library
+dnl $PVM_ROOT/lib/$PVM_ARCH/libgpvm3.a  -  Group function library
