Hi,

The last file is the culprit. There is a GMP installation in /usr/local 
which does not match the GMPXX installation in /usr. You should either 
move the GMP installation in /usr/local/include away (including libs in 
/usr/local/lib), or you need a consistent GMP+GMPXX+MPFR installation in 
/usr/local.
