我在Perl中創建了一個自定義CUPS後端。它在10.7-10.9完美運行，但10.10（優勝美地）顯然有一個新的沙箱功能，阻止我在「/ opt」中包含來自subdir的文件。sandboxd禁止我的自定義後端在OS X上運行Yosemite
歡迎任何建議！
下面是從杯子是error_log：
Can't locate Net/IPP/IPP.pm in @INC (you may need to install the Net::IPP::IPP module) (@INC contains: /opt/msipp [redacted] .) at /usr/libexec/cups/backend/msipp line 73.
下面是從系統日誌中：
sandboxd[286]: ([11381]) perl5.18(11381) deny file-read-metadata /opt/msipp/Net/IPP/IPP.pm
