Subject: Problems installing Ruby on AIX 4.3.3

I'm trying to install Ruby 1.8.6 on AIX 4.3.3 using the IBM's xlc
compiler.  there are a few trivial commas to remove (from eval.c and
parse.y), but the real stumbling block comes later:

    ./lib/fileutils.rb:1278: [BUG] unexpected local variable
    ruby 1.8.6 (2007-03-13) [powerpc-aix4.3.3.0]

    make: The signal code from the last command is 6.

I get the same result if I compile with CFLAGS=-g (rather than the
default -O).  I also tried to compile 1.8.5.  it bombs with:

    ./lib/fileutils.rb:1574: [BUG] terminated node (0x28)
    ruby 1.8.5 (2006-08-25) [powerpc-aix4.3.3.0]

    make: 1254-059 The signal code from the last command is 6.

here, the error with CFLAGS=-g is different:

    ./lib/fileutils.rb:85: NULL pointer given (ArgumentError)
            from ./mkconfig.rb:10:in `require'
            from ./mkconfig.rb:10
    make: The error code from the last command is 1.

it seems to me it takes deeper insight in Ruby's workings than I
currently have to debug this problem, but I'll be happy with any hints
you can provide.
