 Reporter:  edlazarus@…  |      Owner:  macports-tickets@…
     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.2.1
 Keywords:               |       Port:  icewm
-------------------------+--------------------------------
 The error in the config.log is:
 configure:2243: /usr/bin/clang++ --version >&5
 Agreeing to the Xcode/iOS license requires admin privileges, please re-run
 as root via sudo.

 Manually executing the clang++ via sudo and repeating the install command
 will work.
 The script should be corrected to account for this.
