the instructions on http://wiki.linuxcnc.org/emcinfo.pl?GladeVcpSetup yield the following
i've deleted the entire ~/emc2-dev dir created by 'git clone git://git.linuxcnc.org/git/emc2.git emc2-dev'
( three times now )

i avoid 'make menu-install' like the plague, i use  make install ( ive tried make menu-install it cause more errs than what follows )

tomp@gatewayLucid:~$ cd emc2-dev
tomp@gatewayLucid:~/emc2-dev$ . scripts/emc-environment
tomp@gatewayLucid:~/emc2-dev$ cd lib/python/gladevcp/
tomp@gatewayLucid:~/emc2-dev/lib/python/gladevcp$ /etc/init.d/realtime start
tomp@gatewayLucid:~/emc2-dev/lib/python/gladevcp$ gladevcp gladevcp-test.ui
RTAPI: ERROR: version mismatch 0 vs 1
RTAPI: ERROR: bad module ID: -22
HAL: ERROR: could not open shared memory
RTAPI: ERROR: bad module id
gladevcp: HAL component 'gladevcp-test' already exists: Invalid argument

the emc that runs in this dir identifies itselfs as 2.5.0~pre
tomp@gatewayLucid:~/emc2-dev$ emc
EMC2 - 2.5.0~pre

what is this version mismatch ?
how to eliminate it?
