I did a make install at the end. I do not have sudo privileges. Is sudo 
necessary?

The full sequence I am executing is,

>automake
>env LDFLAGS="-L/usr/pkg/lib -R/usr/pkg/lib" CPPFLAGS="-I/usr/pkg/include" 
>./configure --prefix=/u/students/renyu/Masters/ren_static/installdir
>make
>make install

make install creates a lib and include folder in installdir with 
howtoren.pyo, pyc, py, so la (my new block is a howtoren module with the 
one block bin_statistics_mean_f.

I read on the howto write your own block tutorial that you need to get 
python to "see" where your new module is:

"The build tree is everything from topdir (the one containing 
configure.ac) down. The path to the install tree is 
prefix/lib/pythonversion/site-packages, where prefix is the --prefix 
argument to configure (default /usr/local) and version is the installed 
version of python. A typical value is 
/usr/local/lib/python2.3/site-packages.

We normally set our PYTHONPATH environment variable to point at the 
install tree, and do this in ~/.bash_profile or ~/.profile. This allows 
our python apps to access all the standard python libraries, plus our 
locally installed stuff like GNU Radio."

I created ~/.bash_profile and ~/.profile, with contents:

setenv PYTHONPATH 
/u/students/renyu/Masters/ren_static/installdir/lib/python2.5/site-packages/

However I still can't from gnuradio import howtoren.

Any advice?
