ImportError: cannot import name ImmutableSet

After some research I found that when upgrading the module to version 1.2.1 (or newer) the file sets.py, that was used on 1.2.0 or prior versions, still on system and this doesn’t contain ImmutableSet that’s defined as a default bult-in set in the recent versions of MySQLdb.

To solve this problem (tested on Python 2.4 and 2.6) just remove the sets.py from your MySQLdb installation directory.

Minha plataforma utilizada foi um RedHat Enterprise 5 rodando em 64bits, e acabei nao encontrando nenhum pacote pronto e atualizado para a instalacao. Para que nao fosse necessario compilar e instalar tudo manualmente resolvi criar o pacote com base em um spec ja existente e para aqueles que precisarem, vou disponibiliza-lo aqui para download:

Source: pyPgSQL-2.4-0.src.rpm
RedHat Advanced Server 5: pyPgSQL-2.4-0.x86_64.rpm
