mmap error (?) when building clisp-2.38 in freebsd-6.1-release for amd64

[Gautham Ganapathy]

Hi

I am trying to the the clisp-2.38 port to build on freebsd-6.1-release
of amd64. However, it does not build and I found a post saying that it
was marked as broken.

So far I have tried the following. 

1, After running make, the first error that comes up is

gmake: *** No rule to make target `avcall-amd64.lo', needed by
`avcall.lo'.  Stop.

In the Makefile in 'work/clisp-2.38/amd64-portbld-freebsd6.1/avcall',
CPU is set to amd64 and avcall-$(CPU).lo expands to avcall-amd.lo, when
the actual source file is avcall-x64_64.c. Setting CPU to x86_64 fixes
this error

2. The next error is

gmake[1]: *** No rule to make target `vacall-amd64.lo', needed by
`vacall.lo'.  Stop.

There is a similar error in
'work/clisp-2.38/amd64-portbld-freebsd6.1/callback/vacall_r/Makefile'
and is easily fixed

3. However, the third error is beyond me.

./lisp.run -B . -N locale -Efile UTF-8 -Eterminal UTF-8 -Emisc 1:1 -norc
-m 1400KW -x "(and (load \"init.lisp\") (sys::%saveinitmem) (ext::exit))
(ext::exit t)"
Cannot map memory to address 0x4000000000000 .
[spvw_mmap.d:359] errno = EINVAL: Invalid argument.
./lisp.run: Not enough memory for Lisp.
*** Error code 1

Is there any way to fix this? Is this for using mmap? The Makefile for
the port enables the '--disable-mmap' option for amd64
