This has nothing to do with the content of the Makefile, the error is
being reported by the dbdExpand.pl script while it's trying to create
the simDetectorApp.dbd file. I'm not sure what the problem is yet
because I don't have full build of ADCore with all the synApps modules.
It's not necessarily a mismatched brace as the error suggests, that was
just a common cause for the mismatched internal context which is being
reported.

The command is being asked to read in the files simDetectorSupport.dbd
and commonDriverSupport.dbd and to output the fully-expanded result into
the file simDetectorApp.dbd. It is somehow getting confused while doing
that, which is a little strange but the parser does try to keep careful
track of and check its current state.

There are dome debug variables in the Perl code which should help me
track down the problem, but I may not going to be able to get to this
until the end of next week, I'll be away on travel until Thursday.

Heinz: The quickest way for you to continue would be to switch to using
Base-3.14.12.4 (or an earlier 3.14.12 release) instead of 3.15.1, would
that be a possibility? Base-3.15.1 is still fairly new and a lot of
modules have not been built against it yet, so you should be prepared
for a few problems like this if you do need to use it.
