sneaked dependencies on brotli and nghttp2

     Type:  defect                       |     Status:  assigned
 Priority:  Normal                       |  Milestone:
Component:  ports                        |    Version:  2.7.2
 Keywords:  leopard, tiger, snowleopard  |       Port:  curl
-----------------------------------------+------------------------
 Is it possible to make these options a matter of choice rather than
 imposed ones? At least for older systems.

 Dependency on `nghttp2` also introduced another problem on Leopard:
 Macports complains that `nghttp2` cannot be installed as universal:
 {{{
 36-61:~ svacchanda$ sudo port -v -n upgrade curl +universal
 --->  Computing dependencies for curl.
 Error: Cannot install curl for the archs 'ppc ppc64' because
 Error: its dependency nghttp2 cannot build for the required archs.
 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there
 is a bug.
 }}}
 (It is probably possible, however again, now a simple task requires manual
 fixes.)
