installperl revision 7c478bd95313f5f23a4c958a745db2134aa03244
#
# This is a version of the 5.6.1 installperl script that has been modified to
# work correctly as part of the ON build process. The changes are as follows:
# * umask set to 022
# * install locations modified to be relative to $ROOT
# * check for 'make test' being run before install removed
# * executables installed with mode 0555
# * executables only overwritten if different from last build
# * check for other versions of perl in $PATH removed
# * .packlist entries cleaned of $ROOT prefix
# * SCCS directories and .tstamp files ignored on install
# * The contents of the additional contrib_bin directory are installed
#
