...However 'make test' does not run so well. A memory error is thrown, but that does not seem to be resource related. I have over 1gb available on this test server and my ulimits are unlimited:...Thoughts?

Sure, see the bug queue and the matrix

You might try doing the Devel::PPPort dance to see if it makes any difference (probably not)

If you have an app which relies on GHTTP, consider installing an older version of perl and trying to install GHTTP there

Also consider switching app to use LWP instead of GHTTP. Why?

Consider that HTTP-GHTTP-1.07 was released 25 Mar 2002 while perl 5.22.0 was released 2015-Jun-01, a 13 years difference. The latest libghttp itself is from 2001-01-23
