 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.6.4
 Keywords:               |       Port:  qemu
-------------------------+--------------------
 I have been testing the PR https://github.com/macports/macports-
 ports/pull/9955 for building qemu on apple silicon macs. After merging
 this PR into my private port repo I have discovered that the vnc variant
 will fail to build. After removing the two sasl lines that are part of the
 vnc variant it builds as expected.

 a configure log from the failed build is here.
