build failure [scons]

I get this weird error with scons 0.96.90:

$ scons PREFIX=`pwd`/debian SKIPPLUGINS=System install

scons: Reading SConscript files ...

TypeError: EnsureSConsVersion() takes exactly 3 arguments (4 given):

  File "SConstruct", line 11:

    EnsureSConsVersion(0,96,91)

  File "/usr/lib/scons/SCons/Script/SConscript.py", line 534:

    return apply(method, args, kw)

Also, does nsis now require scons 0.96.91 for building instead of just scons 0.96.90? If so, the INSTALL file should be updated.

Yes, scons 0.96.91 is now required. I've updated the documentation, but forgot about INSTALL. It's now updated, thanks.
