 dnl This command can be used to run with the PSPP Perl module after it has been
 dnl built (with "make") but before it has been installed.  The -I options are
 dnl equivalent to "use ExtUtils::testlib;" inside the Perl program, but it does
 dnl not need to be run with the perl-module build directory as the current
 dnl working directory.

-dnl XXX "libtool --mode=execute" is probably better than setting
-dnl LD_LIBRARY_PATH.
