after an svn update in the release directory
scons doesn't work anymore.
i have revision 1433.

this is the output from scons:
koblitz@pcbelle06:/remote/pcbelle06/koblitz/belle2/basf2/release$ scons
scons: reading sconscript files ...
checking for belle ii environment setup...(cached) yes
checking for local release setup...(cached) yes
checking for xml2-config...(cached) yes
checking for graphics packages...(cached) no
checking for root-config...(cached) yes
belle ii externals directory is not set up.
-> execute "setuprel" in your local release directory.
koblitz@pcbelle06:/remote/pcbelle06/koblitz/belle2/basf2/release$ 


and yes, i have done setuprel at least three times. i also started with a fresh new shell, but this didn't change the outcome of scons.
