[oe] xmonobut-0.4.1.tar.gz missing checksum

[Ajit Limaye]

Hi:
 
I am building a xii-image, using the following conf file for bitbake:
 
DL_DIR = "${OEBASE}/sources"
BBFILES = "${OEBASE}/openembedded/recipes/*/*.bb"
MACHINE = "overo"
DISTRO = "angstrom-2008.1"
BBDEBUG = "yes"
DEBUG_BUILD = "1"
INHIBIT_PACKAGE_STRIP = "1"
BBINCLUDELOGS = "yes"
 
I get the following error:
 
NOTE: Missing checksum
ERROR: xmonobut-0.4.1:

I checked the familiar.handhelds.org website and discovered that rc2 has
been superceded by a stable release (v0.8.4), so I modified the source
path defined in  openembedded/recipes/xmonobut/xmonobut_0.4.1.bb from:
familiar.handhelds.org/source/v0.8.4-rc2/sources/xmonobut-${PV}.tar.gz
to: /familiar.handhelds.org/source/v0.8.4/sources/xmonobut-${PV}.tar.gz
but I still get the same error. 
 
Any suggestions regarding what I am doing wrong or what else I can try
would be greatly appreciated. 
 
Thanks.
