Comment (by ballapete):

 Next releaaes of `libgcrypt` will make use of the `getentropy()` function.
 This means that `Portfile` will need to have

 {{{
 PortGroup           legacysupport 1.0
 }}}

 A problem exists since the developers do not know whether and when a
 symbol `_getentropy` was introduced to some `dylib` by Apple. Another
 question is whether a guard in `Legacy Support` exists that can be used by
 the C pre-processor to either use or bypass `Legacy Support` code…
