# This script takes as input a path to a prototype space of files that are to be
# encapsulated in Solaris packages.  The installation must include both 32 and
# 64 bit libaries and prefixed in the correct manner.
#
# The steps to build are as follows using vpaths:
# % cd ompi-trunk
# % ./autogen.sh
# % mkdir -p vpath/64 vpath/32/ vpath/proto
#
# (sparc build)
# % cd vpath/64

#    -fpp -xarch=v9" FCFLAGS="-xarch=v9 -KPIC" --disable-binaries \
