Erro na instalação do erp5 - erro no buildout

[dhcp]

Tentando instalar  o ERP5 em uma máquina Ubuntu 10.4, ia tudo bem até darm essa mensagem de erro, ao configurr  o buildout, dá essa mensagem de erro. TEntei baixar  o pacote correspondente no Sinaptycs, baixei mas continua o erro no mesmo lugar...........

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:
