# I wish there were a more straightforward way to do this. But I can't
# seem to find the right internals in the perl programming language.
# Also, this program is only a "modest" effort to LOOK and see whether
# necessary perl system dependencies are present. I do not yet
# try to actually run tests against each needed perl module.
# --------------------------------- Make sure the perl version is suitably high
my $ret=system("find --version 1>/dev/null");

die "DEPENDENCY FAILURE: LON-CAPA requires perl version >= 5.005.\n";

# ------------------------------------------ Make sure we have the find command
my $ret=system("find --version 1>/dev/null");
if ($ret) {
die "DEPENDENCY FAILURE: A test program requires the GNU ".
"'find' utility.\n";
}
# ----------------------------------------- Read in all the system perl modules
print "Scanning for perl modules...\n";
