I've pushed an updated version of the h2iscey model, that includes some missing termination of unused channels.  I have also rebuilt and installed this model, both without issue:

controls@h2build ~ 0$ cd /opt/rtcds/lho/h2/rtbuild-2.4.1
controls@h2build rtbuild-2.4.1 0$ make h2iscey
command is make h2iscey
...
Successfully compiled
*********************
make succeeded
log file is /opt/rtcds/lho/h2/data/buildlog/h2iscey_2012_06_23_15:06:52
controls@h2build rtbuild-2.4.1 0$ make install-h2iscey
command is make install-h2iscey
...
make succeeded
log file is /opt/rtcds/lho/h2/data/buildlog/install-h2iscey_2012_19_23_15:19:33
controls@h2build rtbuild-2.4.1 0$

NOTE: I have not restarted the model.  I'll leave it to someone on site to restart the model.
