#48051: Installing a port +universal needlessly reinstalls recursive dependencies
+universal
----------------------+--------------------------------
 Reporter:  larryv@…  |      Owner:  macports-tickets@…
     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:
Component:  base      |    Version:  2.3.99
 Keywords:            |       Port:
----------------------+--------------------------------
 I have `zlib` installed. It only has an extract dependency on `xz`, which
 I also have installed.
 {{{
 % port -v deps zlib
 Full Name: zlib @1.2.8_0
 Extract Dependencies: bin:xz:xz
 % port -v installed xz zlib
 The following ports are currently installed:
   xz @5.2.1_0 (active) platform='darwin 15' archs='x86_64'
   zlib @1.2.8_0 (active) platform='darwin 15' archs='x86_64'
 }}}

 If I try to install `zlib +universal`, I don’t expect `xz` to be
 reinstalled because it’s just an extract dependency. Indeed, this doesn’t
 happen.

 Cool. I don’t actually need a universal `zlib`, so I reactivate the old
 one and uninstall the universal one.

 ----

 Now I want to install `openssl +universal`. It has a library dependency on
 `zlib`.
 {{{
 % port -v deps openssl
 Full Name: openssl @1.0.2c_0
 Library Dependencies: port:zlib
 % port -v installed openssl xz zlib
 The following ports are currently installed:
   xz @5.2.1_0 (active) platform='darwin 15' archs='x86_64'
   zlib @1.2.8_0 (active) platform='darwin 15' archs='x86_64'
 }}}

 So I expect `zlib` to be rebuilt universal before `openssl` is built. Like
 before, I don’t expect `xz` to be reinstalled because it’s just an extract
 dependency. This time, I am sorely disappointed.
