Just got a VPS and looking to get the xhprof php extension installed.
Using the standard install instructions from http://techportal.ibuildings.com/2009/12/01/profiling-with-xhprof/
(using the phpize for php5.3 and php-config for 5.3)
I get the extension building/installing fine, but "make test" fails. xhprof shows up in my phpinfo(), but using xhprof_enable generates and internal server error.
Anyone out there get xhprof installed successfully? did you have to do anything special?
Any ideas where to look to get this extension installed?
