syntaxerror

hello 
I'm newby with aap.
to compile an application (WhatOS) with cygwin an xfree on windwos XP

Here is the beginning of the file .aap called by aap configure where it seems to be a syntax error

#S,configure :

libboost_python = $_recipe.LIB_BOOST_PYTHON_DIR/$_recipe.LIB_BOOST_PYTHON

:python

# on windows, PATH is used to find dlls

if sys.platform == 'cygwin':

LD_LIBRARY_PATH = 'PATH'

else:

LD_LIBRARY_PATH = 'LD_LIBRARY_PATH'



The error message is:

bash-2.05b$ aap configure
Aap: Error in recipe "/home/Thierry Poidras/whatos-1.0.3/whatos/whatos/syscheck.aap" line 3:
     aap_assign(3, globals(), 'libboost_python', "$_recipe.LIB_BOOST_PYTHON_DIR/$_recipe.LIB_BOOST_PYTHON_DIR", '=', '')
     ^
