#51889: gmp fails to build when path to selected xcode app contains parenthesis

     Type:  defect  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.3.4
 Keywords:          |       Port:  gmp
--------------------+--------------------------------
 When xcode is installed to a path including parenthesis (for example:
 '/Applications/Xcode 7.3 (old)'), the paren characters are not escaped
 correctly, and build of gmp fails. Symlinking to the directory continues
 to resolve to the absolute path to tools, and still fails. Renaming the
 xcode directory to not include parenthesis, and re-selecting it with
 'xcode-select' fixes the build.

 Please correctly shell-escape paths with unusual characters when selecting
 make, gcc, etc.
