#50854: scons incorrectly builds projects, serf1 unexpectedly changed dylib
versions with just a revbump for OpenSSL
------------------------+--------------------------
 Reporter:  jeremyhu@…  |      Owner:  ryandesign@…
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.3.4
 Keywords:              |       Port:  scons
------------------------+--------------------------
 serf1 was recently revbumped to rebuild against an updated OpenSSL.  In
 doing so, other ports on my system broke because the dylib version of
 libserf changed:

 /tmp/r1 $ tar xjf .../serf1-1.3.4_1+universal.darwin_15.i386-x86_64.tbz2

 Timestamps of when they were built:

 -rw-r--r--   1 root admin 424529 Oct 17 00:33
 serf1-1.3.4_0+universal.darwin_15.i386-x86_64.tbz2
 -rw-r--r--   1 root admin 410869 Mar 10 11:09
 serf1-1.3.4_1+universal.darwin_15.i386-x86_64.tbz2

 The only change to the serf1 port since Oct 17 was the revbump.

 However, scons was recently updated from 2.3.4 to 2.4.1, and that
 certainly seems like the likley cause.  I'll give a try reverting it.
