Even if I don't set $LDFLAGS in my build script, I still have LDFLAGS
set in my ~/.bash_profile.

Here is the my build script and the build output. It
still gives me errors. What is wrong with it?

$ cat ~/notes/install/numpy/build
#!/usr/bin/env bash

#export LD_LBRARY_PATH=
#export CPPFLAGS="-I$HOME/utility/linux/opt/Python-2.6.2/include/python2.6"
#export LDFLAGS="-L$HOME/utility/linux/opt/Python-2.6.2/lib -lpython2.6"

#export CPPFLAGS=
#export LDFLAGS=

export PATH=$HOME/.bin/misc:$HOME/utility/linux/opt/Python-2.6.2/bin:$HOME/utility/linux/opt/gcc-4.3.4/bin:/usr/local/bin:/usr/bin:/bin
#echo $PATH
gcc --version
python --version

python setup.py build --fcompiler=gnu95 | tee build_output ;
sendmail.sh build_output

$ tail -20 build_output
