Create extension tablefunc fails with "wrong ELF class: ELFCLASS32"

[Jan Mechtel <jmechtel@xxxxxxxxx>]

Our webhoster moved us to a 64Bit CentOS. I installed postgresql-9.1.3 from source.

I run into trouble when trying to create the tablefunc extension

b2blogin_mailrocket=# create extension tablefunc;

ERROR:  could not load library "/home/b2blogin/lib/postgresql/tablefunc.so": /home/b2blogin/lib/postgresql/tablefunc.so: wrong ELF class: ELFCLASS32

On google I didn't only find some clues, that this seems related to 64bit vs. 32bit.

Please help or point me in the right direction.
