Dear numpyers,

I am trying to install numpy 1.3 with my own version of python 2.5. I got
stuck with following error:
*building 'numpy.core.multiarray' extension
compiling C sources
C compiler: gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall
-Wstrict-prototypes -fPIC

creating build/temp.linux-x86_64-2.5
creating build/temp.linux-x86_64-2.5/numpy
creating build/temp.linux-x86_64-2.5/numpy/core
creating build/temp.linux-x86_64-2.5/numpy/core/src
compile options: '-Ibuild/src.linux-x86_64-2.5/numpy/core/src
-Inumpy/core/include -Ibuild/src.linux-x86_64-2.5/numpy/core/include/numpy
-Inumpy/core/src -Inumpy/core/include
-I/home/cmb-01/lxia/usr/include/python2.5 -c'
gcc: numpy/core/src/multiarraymodule.c
gcc -pthread -shared
build/temp.linux-x86_64-2.5/numpy/core/src/multiarraymodule.o -L. -lm -lm
-lpython2.5 -o build/lib.linux-x86_64-2.5/numpy/core/multiarray.so
/usr/bin/ld: cannot find -lpython2.5
collect2: ld returned 1 exit status
/usr/bin/ld: cannot find -lpython2.5
collect2: ld returned 1 exit status
error: Command "gcc -pthread -shared
build/temp.linux-x86_64-2.5/numpy/core/src/multiarraymodule.o -L. -lm -lm
-lpython2.5 -o build/lib.linux-x86_64-2.5/numpy/core/multiarray.so" failed
with exit status 1*

I guess it is because the ld can find the libpython2.5.so; So i tried
following methods:
1. $export LD_LIBRARY_PATH = $HOME/usr/lib # where my libpython2.5.so is in
2. edited the site.cfg file so that:
    library_dirs = ~/usr/lib
    include_dirs = ~/usr/include
    search_static_first = false

Both methods don't work. But when I remove the -lpython2.5 flags from the
compiling command, the command go through without problem. But I don know
where to remove this flag in the numpy package. I ran out choice now and
thus I want to get help from you. Thanks for any advice.
