Comment (by cal@…):

 A couple of lint warnings:
 {{{
 $ port lint --nitpick
 --->  Verifying Portfile for ChezScheme
 Warning: Line 5 should be a newline (after PortSystem)
 Warning: Line 11 seems to hardcode the version number, consider using
 ${version} instead
 Warning: Line 25 has trailing whitespace before newline
 Warning: no license set
 --->  0 errors and 4 warnings found.
 }}}

 A couple of comments:

  - Your whitespace doesn't match the modeline; we usually use 4 spaces for
 indentation, but your Portfile uses a mix of spaces and tabs.
  - Instead of `build.target-delete all`, I'd just use `build.target`
 (without anything after it), which sets `build.target` to empty, like you
 did it for `configure.pre_args`.
  - The port uses curl to download additional files in the build phase. Can
 this be avoided?
  - The port seems to unconditionally use `gcc` to compile. We want it to
 use `$CC` from the environment and pay attention to our `$CFLAGS` (which
 it seems to do) and `$LDFLAGS`.
  - The port seems to build its own copy of zlib. It should use MacPorts'
 zlib instead. Additionally, the copy of zlib requires Xlib headers which
 causes the build to fail ![1] and compiles a library that is only suitable
 for installing in `/usr/local/lib` ![2]
