[Scons-users] SCons freezes

[Gary Oberbrunner]

This is related to the .sconsign.dblite file I think, where SCons records
the build signatures from previous builds.  Could be a permissions issue or
file corruption due to the previous error.  I recommend deleting that file,
which will cause a complete rebuild, and then you should be OK.
