MacPorts的安裝錯誤

Question

我使用的MacPorts並獲得以下錯誤Valgrind的安裝：

---> Computing dependencies for valgrind 
---> Building valgrind 
Error: org.macports.build for port valgrind returned: command execution failed 
Please see the log file for port valgrind for details: 
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_valgrind/valgrind/main.log 
To report a bug, follow the instructions in the guide: 
    http://guide.macports.org/#project.tickets 
Error: Processing of port valgrind failed 

這裏是日誌文件：

我已經安裝了Valgrind的（3.7，舊版本）。這可能是一個問題嗎？

正如日誌中所述，您遇到的錯誤之一是您尚未接受Xcode命令行工具的許可協議。爲此，請在終端中鍵入xcodebuild -license。
