: So how should I set up lang/sbcl?  In theory it could cross-compile 
: itself to another machine arch or OS, but that would probably be a very 
: difficult thing to do in pkgsrc.  (It requires several back and forth 
: passes running tools on the host and target to bring things up.) 
: However, SBCL is pretty much required to build itself on a native 
: platform.  In theory, CLisp could also do the job, but reality seems to 
: be somewhat different. Other Common Lisp systems may (or may not) be 
: able to the job also, but we don't have any in pkgsrc.

  None of your suggested solutions work if I don't already have a
binary package for sbcl.  Thus, none of them work on a fresh install
or in a bulk build.

: Should I have lang/sbcl in USE_TOOLS, BOOTSTRAP_DEPENDS, or 
: BUILD_DEPENDS?  And to install the package, lang/sbcl needs to be 
: removed first.  Should I just add a pre-install target that runs 
: "pkg_delete sbcl"?

  You should create a tarball containing the binaries (and support
files) needed to bootstrap sbcl, add those to DISTFILES, and extract
those to WRKDIR for building the package.
