[Wine] "Bus Error" Under Mac OS X x86 with Wine 0.9.20

[dackz]

I'm trying to run Wine 0.9.20 under OS X x86 and I'm getting nothing
but "Bus Error" when I run any win32 program via Wine. Here is some
relevant environment info:

OS: Mac OS X 10.4.7

I built and installed Wine with a DarwinPorts portfile that I created.
Here's what it looks like:

platform darwin powerpc {
    ui_msg "Wine is not supported on PowerPC"
    exit 1
}

It built and installed wine just fine. It's just when I run it that I
get "Bus Error". I decided to load up gdb to see what it thought, and
it had this to say:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x7ffde064
thread_init () at thread.c:228

$1 = (PEB *) 0x7ffde000

dlls/ntdll/thread.c:220-228 has this:

    /* reserve space for shared user data */

    addr = (void *)0x7ffe0000;
    size = 0x10000;
    NtAllocateVirtualMemory( NtCurrentProcess(), &addr, 0, &size,
MEM_RESERVE, PAGE_READONLY );

    /* allocate and initialize the PEB */

    addr = NULL;
    size = sizeof(*peb);
    NtAllocateVirtualMemory( NtCurrentProcess(), &addr, 1, &size,
                             MEM_COMMIT | MEM_TOP_DOWN, PAGE_READWRITE );
    peb = addr;

    peb->NumberOfProcessors = 1;

At this point, I'm stumped. Is there something wrong with my portfile
that's causing problems? The only thing I can think of is that it's
using incompatible versions of libraries that Wine requires, but I'd
hope that the configure script would catch something like that. Either
way, these are versions I'm using from DarwinPorts:

  fontforge @20060125_0 (active)

  gettext @0.14.6_0 (active)

Any ideas?
