Unable to load dynamic library - http_errno_description is Unknown

[dustin-hawkins]

I have built php-git2 on a CentOS 6.8 box following the instructions. The build is successful, with no errors.

Upon loading PHP, I get the following:

Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/git2.so' - /usr/lib64/php/modules/git2.so: undefined symbol: http_errno_description in Unknown on line 0

It looks like its unable to find one of the dependencies provided by: libgit2/deps/http-parser

I have it loading at the very end of the PHP ini, after all other modules are loaded. I have tried ./configure with and without the --enable-git2-debug, but have the same issue.

Any thoughts on how I screwed up the build process?
Thanks,
