Cfengine 2.1.10 - variable not set by ExecResult ?

[Christian Korschan]

I have the following problem when using one of the following
statements in control:

   osversion = ( ExecResult(/bin/echo `/bin/uname -s`-`/bin/uname -r`) )
   osversion = ( ExecResult(PATH/osversion) )
   osversion = ( "exec PATH/osversion" )
   osversion = ( "exec /bin/echo `/bin/uname -s`-`/bin/uname -r`" )

osversion is not set at all (it's empty) in a copy statement like

copy:
  any::
    $(masterfiles)/site/$(site)/$(osversion)/etc/defaultrouter 
dest=/etc/defaultrouter owner=root group=sys mode=444 type=checksum 
stealth=on

although cfagent's debug (-d9) output shows

...
Scanning variable osversion
GetMacroValue(main,osversion)
EXPAND $(osversion) -> SunOS-5.9
   295 : osversion=SunOS-5.9

Everything works as expected when osversion is set in cfagent's
executing environment with "export osversion=`uname -s`-`uname -r`"
and ExecResult is not used. Obviously this is weird because one has
to take care that osversion *is* set in the executing environment, but
using ExecResult would make it clear in cfagent.conf what osversion is 
set to without having to care about what has (not) been done
outside cfagent.conf

Does anybody know how to make ExecResult work in Cfengine 2.1.10 ?

Thanks
