Problemas na instalação do MrBayes 3.2.1 no Ubuntu 13.04

[GuilhermeFreitas]

Estou com problema para instalar o programa MrBayes 3.2.1 no Ubuntu 13.04.
É um programa que tem que ser compilado a partir do código fonte.
Já tenho os pacotes g++, gcc, autoconf, MPI compiler, libc6-dev, build-essential...
E continuo com o seguinte erro quando executo o comando ./configure:

g@freitas:~/mrbayes/mrbayes_3.2.1/src$ ./configure
checking for gcc... MyCompiler
checking whether the C compiler works... no
configure: error: in `/home/guilherme/mrbayes/mrbayes_3.2.1/src':
configure: error: C compiler cannot create executables
See `config.log' for more details


o config.log fornece a seguinte msg:
