I am running CentOS 6.4 64-bit with PHP 5.5.4
When trying to install mcrypt, I'm getting
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 requires v 2.14 of glibc? If so, that would make it incompatible with CentOS, which comes with glibc 2.12!
Damn! Sorry about the bad formatting...didn't see formatting help while typing...certainly didn't intend to shout out the error message here...
