Computer locks up during "port install" process

[Murdachaew, Garold]

Dear macports experts,

I have today installed macports on my desktop mac (Mac OS X 10.5.8).  I am thus a macports newbie so please bear with me if these are rather basic questions.

I have  successfully used macports to obtain various packages, e.g.:

$ sudo port install g95

etc.

Now I am trying to install openmpi.  However, the computer locks up (for over an hour, until I did a hard reboot) at the point of attempting to install a supposedly needed dependency, a new gcc:

$ sudo port install openmpi
Password:
--->  Computing dependencies for openmpi
--->  Staging gcc43 into destroot

Is it trying to re-compile the kernel with gcc43?  I already have a working version of gcc (granted, an older version):

$ gcc -v
Using built-in specs.
Target: i686-apple-darwin9
Configured with: /var/tmp/gcc/gcc-5490~1/src/configure --disable-checking -enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/c++/4.0.0 --with-slibdir=/usr/lib --build=i686-apple-darwin9 --with-arch=apple --with-tune=generic --host=i686-apple-darwin9 --target=i686-apple-darwin9
Thread model: posix
gcc version 4.0.1 (Apple Inc. build 5490)

Is there a way to have openmpi use this system version of gcc? (and the g95 already installed by macports)?

Thank you in advance for your assistance.
