Dunno if this helps this particular user, but it helped me personally…
I use Easy-CGI for my host provider and was running into this same error when I went to upgrade from 2.3.1 to 2.3.2. Easy-CGI allows you to use either PHP v4.4.4 or 5.2.4. Through their configuration menus, I discovered I was using 4.4.4 – once I changed it to 5.2.4, the error message went away. So something must be different between how Easy-CGI has 4.4.4 vs. 5.2.4 configured.
