Problems on gimp.app updating

[Fabrizio Bartolomucci]

This the sequence of errors I get:

--->  Building gimp-app
Error: Target org.macports.build returned: shell command "cd 
"/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_gimp-app/work/ScriptExec" 
&& xcodebuild  -alltargets -configuration Deployment build 
OBJROOT=build/ SYMROOT=build/ " returned error 1
Command output: (NOTE: project ScriptExec was written by an older Xcode 
version (39) -- temporarily upgrading it (without modifying project file))
