I complied PSAD from source, compilation went smoothly however when I run this command:
sudo psad --sig-update
I got this:
Can't load '/usr/lib/psad/x86_64-linux-gnu-thread-multi/auto/Date/Calc/Calc.so' for module Date::Calc: /usr/lib/psad/x86_64-linux-gnu-thread-multi/auto/Date/Calc/Calc.so: undefined symbol: DateCalc_Day_of_Week_to_Text_ at /usr/lib/perl/5.18/DynaLoader.pm line 184.
