#49169: port selfupdate breaks when going from 2.3.3 to 2.3.4

     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.3.4
 Keywords:                |       Port:
--------------------------+--------------------------------
 I am getting an error when running port selfupdate and this machine's self
 update was reliable from this network in the past. This ticket should be
 used instead of the poorly formatted earlier attempt, Ticket #49168.
 Please note that my rsync appeared to work, hence it is likely different
 than Ticket #49140, which has a similar complaint but probably a different
 cause. Here I try it twice (note the user name is sanitized), the second
 time with the -v flag. Interestingly I the error appears to complain about
 the C compiler unable to create executables, but port installed shows
 "gcc49 @4.9.3_0 (active)", I've appended the full list to the end of this
 description. The file
 /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/base/config.log
 is attached.

 Now the output of port installed.  Note that gcc 4.9 appears to be
 installed.
