Yes, and in the meantime, I figured out what went wrong. First, the index was built with the old tool. Ok, I've rebuilt it with the 5.6.1 tool, and the MacPerl app was able to read it, but Shuck wasn't. I looked at Shuck with the debugger, and something was going wrong with a fstat() call in db's mpool.c. When the mode this fstat()returns for "MacPerl Help" is checked with a S_ISREG(), this call doesn't return true (i.e. it's not a regular file -- huh?). It turned out that linking against both

"{GUSI}lib:GUSI_MPW.MrC.Lib"  and
"{GUSI}lib:GUSI_Core.MrC.Lib" 

causes this error (I'm not sure why). However, when I link against "{GUSI}lib:GUSI_Core.MrC.Lib" only, Shuck is able to read the index, i.e. fstat() reports the right file mode. So when you try to build with CW, be aware of this.

I will commit the changes soonish.
