gmp-6.1.2: Configurating gmp failed

[Limbo999 (Franziska Wegner)]

Error occurs when trying to install gmp-6.1.2. I already tried "sudo port clean gmp" and "sudo port install gmp". "macosx_deployment_target" is not set in macports.conf.

2 errors generated.
configure:10624: $? = 1
failed program was:
/* This test rejects g++ 2.7.2 which doesn't have <iostream>, only a
    pre-standard iostream.h. */
#include <iostream>

/* This test rejects OSF 5.1 Compaq C++ in its default pre-standard iostream
   mode, since that mode puts cout in the global namespace, not "std".  */
void someoutput (void) { std::cout << 123; }

int main (void) { return 0; }
configure:10650: result: no, std iostream
configure:10666: error: C++ compiler not available, see config.log for details

could you please check to make sure you don't have anything, esp a copy of Availability.h, anywhere in the /usr/local/ directory and all it's subdirectories?

Thanks, K
