Use

./configure --enable-longtests

See the internals.* documentation for more information.

    ./configure --enable-longtests

But when I run "make test"

It doesn't run the regression tests and here is the output message:

/Library/Developer/CommandLineTools/usr/bin/make -C test_regress
/usr/bin/perl driver.pl -j 0 --vlt --vltmt --dist
driver.pl: Found 8 cores, using -j 9

dist/t_EXAMPLE: ==================================================

dist/t_EXAMPLE: %Skip: Skip: scenario 'dist' not enabled for test
Tests passed!

The first lines are correct. Nothing at all after that?

That's all I got.

Perhaps the perl IPC::Forker package is exiting early, is there something special about your system like weird security settings?

You can comment out this line, though it'll make tests take 9 times longer.

I have tried that, can't see any changes. All the same. I have attached the LOG files. Hope it will be helpful

See what was wrong, this should be fixed in git, thanks for the bug report & debugging.

Note you should cpan install Parallel::Forker for better testing, it will now also tell you this.
