senhor Tim Prince,

Gostaria de agradecer o email que me enviou sobre openmpi, na verdade,
estou tentando compilar o Regcm 4, e quando uso o comando, make regcm,
aparece um erro "mpif90" por isso fui em busca da solução do problema do
openmpi,utilizo um computador de plataforma 64 bits com sistema operacional
ubuntu 10, nao consigo instalar de forma alguma o open, faço passo a passo.

1- ./configure FC=ifort F77=ifort CC=icc CXX=icpc

2-make all

3 sudo make install all

os passos 1 e 2 operam normalmente, mas quando uso o comando make install
aparece o erro que nao consigo solucionar.

se tiver alguma idéia sobre isso, por favor me ajude.

obrigado
