 Insights, anyone?

 I think the mystery is almost solved. I'm already working on PR to fix
 that.

 {{{cctools}}} on Yosemite and newer systems [https://github.com/macports
 /macports-
 ports/blob/8bdfc652f5234b347edd4a0f73c28e271f69a29a/devel/cctools/Portfile#L118
 depends on llvm-9.0], which leads to a dependency cycle on {{{xar ->
 openssl}}}. This package is **only** needed on Snow Leopard, while
 everything works fine on other machines.
