I am not sure if this is a bug or just not documented. The path
specification can be a regular expression, thus the + character needs to
be escaped here.

Unfortunately, you need to escape this once for Tcl and another time for
the regex engine, which results in this ugly, but working dependency
specifiation:

  depends_run path:lib/libstdc\\\\+\\\\+\\\\.dylib:libstdcxx

Actually, the dot would always need to be escaped in all uses of path:
specifications as shown above... Do we even have a use case for a regex
in path:?
