While building GNOME with jhbuild I receive the following:

checking for gnomeapplet module... ./configure: line 22330:  8158 Aborted                 ( $PYTHON -c '
try:
    import gnomeapplet
except ImportError, e:
    if str(e).find("gnomeapplet") >= 0:
          raise
except:
    pass
' ) 2>&5
no
configure: error: gnomeapplet Python module required to build deskbar

Looking at the config.log file I find the following:

configure:22299: checking for gnomeapplet module
configure:22309: $PYTHON -c '
try:
    import gnomeapplet
except ImportError, e:
    if str(e).find("gnomeapplet") >= 0:
          raise
except:
    pass
'
GTK Accessibility Module initialized

configure:22320: $? = 134
configure:22325: result: no
configure:22327: error: gnomeapplet Python module required to build deskbar

Someone have any advice in how to resolve this?
