Hi,
I am new to BGL as well as python and  need to install BGL support for 
Python.

I followed the following steps for the installation.

1. downloaded Boost current : 1.49.0: & bootstrap with 
--with-python=/usr/bin/python
2. downloaded bgl-python from  'svn co 
https://svn.osl.iu.edu/svn/projects/viz/bgl-python'
3. set the environ variable BOOST_ROOT to  "dir head of Boost1_49_0 src 
code"
4. run bjam in bgl-python. dir

I get 2 compilation errors.

...failed gcc.compile.c++ bin.v2/gcc-4.6/release/graphml.o...
...skipped <pbin.v2/gcc-4.6/release>_graph.so for lack of 
<pbin.v2/gcc-4.6/release>graphviz.o...
...failed updating 2 targets...
...skipped 1 target...
===

The errors are related to read/write_graphviz()  read/write_graphml()  in 
files graphviz.cpp and graphml.cpp   :  Anyone who have fixes are work 
around, kindly please let know.

Thanks a lot, in advance.

Example error output given below:
