Installing mcrypt is proving to be a major issue.
Getting the error
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so' - /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /usr/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so)
Does this mean that mcrypt needs glibc 2.14 or higher?:-?
If so, that would mean CentOS 6.4 can't run PHP 5.5.4 with mcrypt, and that just seems far-fetched.
(CentOS 6.4 comes with glibc 2.12 and everyone strongly recommends against upgrading it)
