[LAU] Supercollider error

[Fons Adriaensen]

Any SC experts out there ?

I'm trying to install SuperCollider (from the AUR package) and get
the following rather uniformative error:

fons at c252:~> sclang
init_OSC
compiling class library..
        NumPrimitives = 532
        pass 1 done
ERROR: There is a discrepancy.
numClassDeps 0   gNumClasses 80

That's without any ~/.sclang.cfg or ~/.sclang.sc.

Strange thing is I did exactly the same yesterday evening on another
system, using the same package, and everything works fine there.

Anyt help appreciated !
