Unable to load dynamic library mhash.so

I’ve been procrastinating on fixing this annoying error from PHP on Ubuntu 10.04:

PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/lib/php5/20090626/mhash.so’ – /usr/lib/php5/20090626/mhash.so: cannot open shared object file: No such file or directory in Unknown on line 0

The fix is to purge the mhash package:


sudo dpkg -P php5-mhash

Had I only known the fix was this simple, I would’ve fixed it much sooner.

Here is the official bug report:
