[CLAM] compile question

[Pablo Colapinto]

Can't find any earlier errors. 

I wonder where the PKG_CONFIG_PATH is set.
Is it imported from the Environment?  I don't see where.
Can I set it manually doing 
opts.Add('PKG_CONFIG_PATH','/opt/local/bin/') or something?
I don't really know python yet . . .

I copied this from the SConstruct File:
note the last opts.Add line of code
---------------------
def load_config_file_to_env( env, dir ):
    opts = Options(dir+'/flags.conf')
    opts.Add( 'CPPPATH', 'CPP PATH')
    opts.Add( 'CCFLAGS', 'CC FLAGS')
    opts.Add( 'CPPFLAGS', 'CPP FLAGS')
    opts.Add( 'LIBPATH', 'LIB PATH')
    opts.Add( 'LIBS', 'libs to link')
    opts.Add( 'LINKFLAGS', 'LINKFLAGS') # This one added because on Mac 
OS X we need additional '-framework OpenGL && AGL'
    opts.Add( 'pkg_config_available', 'PKG Config Available', 'False')
    opts.Update(env)

def save_config_file_from_env( env, dir ):
    # workaround due to bug in scons (if we add the flag after loading 
it will add "" to the new flagand will fail
    opts = Options()
    opts.Add( 'CPPPATH', 'CPP PATH', '')
    opts.Add( 'CCFLAGS', 'CC FLAGS', '')
    opts.Add( 'CPPFLAGS', 'CPP FLAGS', '')
    opts.Add( 'LIBPATH', 'LIB PATH', '')
    opts.Add( 'LIBS', 'libs to link', env['LIBS'])
    opts.Add( 'LINKFLAGS', 'LINKFLAGS', '') # This one added because on 
Mac OS X we need additional '-framework OpenGL && AGL'
    opts.Add( 'pkg_config_available', 'PKG Config Available', 'False')
    opts.Save(dir+'/flags.conf', env)
