While compiling (linking) wxd on OSX 10.6 with dmd2 v2.050

/usr/bin/ranlib: object: ../libwxd.a(Accelerator.o) malformed object
(LC_SEGMENT command 0 filesize field greater than vmsize field)

in dmd/backend/machobj.c :
search for 
segment_cmd.vmsize

change :
    segment_cmd.vmsize = vmaddr;
    segment_cmd.filesize = foffset - segment_cmd.fileoff;

to :

    segment_cmd.vmsize = vmaddr;
    segment_cmd.filesize = foffset - segment_cmd.fileoff;
    if (segment_cmd.filesize > vmaddr)
        segment_cmd.vmsize = segment_cmd.filesize;

and then rebuild dmd2

And the problem is fixed, although I doubt that this is the proper way to fix
it.
