Greetings, I am by no means an installation expert. However, looking over your build log it looks like the Python you are using is the one that came with Mac OS X. My experience has been that it is necessary to install the Mac OS X Python version available at http://www.python.org/download/. The one that comes installed with OS X seems to be a custom job by Apple. However, I am sure that the true installation experts on the list will have better information or advice for you.

Dear all,

I am running OS X 10.4.11, and when I run gcc -v, I get:

Using built-in specs. Target: powerpc-apple-darwin8 Configured with: /private/var/tmp/gcc/gcc-5026.obj~19/src/configure -- disable-checking --prefix=/usr --mandir=/share/man --enable- languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^+.-]*$/ s/$/-4.0/ --with-gxx-include-dir=/include/gcc/darwin/4.0/c++ -- build=powerpc-apple-darwin8 --host=powerpc-apple-darwin8 -- target=powerpc-apple-darwin8 Thread model: posix gcc version 4.0.0 (Apple Computer, Inc. build 5026)

However, when I move into the numpy-1.0.4 directory and run python setup.py install, I get hundreds of error messages which appear to relate to my C compiler. Here is the output with lots of similar C messages in the middle omitted:

I know that my C compiler works, because I do my research in C on a regular basis. Does anybody have any ideas?
