sbcl: fix build on Lion

[jim@…]

Could you please add a clause for Darwin 11 in the port file?

I added the clause below and SBCL installed perfectly.

Thanks,
Jim

platform darwin 11 i386     {
		   set bootversion 1.0.48
		   distfiles-append ${name}-${bootversion}-x86-darwin-binary${extract.suffix}
		   checksums-append ${name}-${bootversion}-x86-darwin-binary${extract.suffix} \
                        md5     5a3fe53829c6c9f589f17db31210e2ce \
                        sha1    c4c6aa31e58767364c36ca509e06cf92c7b2e293 \
                        rmd160  9f7e7a7c3d4ed35540c6c81962052fc13ee2cd9b

		   global host_lisp
		   set host_lisp	"\"${workpath}/${name}-${bootversion}-x86-darwin/src/runtime/sbcl --core ${workpath}/${name}-${bootversion}-x86-darwin/output/sbcl.core --disable-debugger --sysinit /dev/null --userinit /dev/null\" "
