Severity: important

(2) Description of problem
When I build bcc, there exists the following build error:
[ 34%] Generating bcc.o
/usr/bin/luajit: /usr/share/luajit-2.1.0-beta3/jit/bcsave.lua:240: cannot convert 'nil' to 'unsigned short'

git clone https://github.com/iovisor/bcc.git
mkdir bcc/build; cd bcc/build

(4) Additional info
I just replace the following old file [1] with the latest new file [2],
then the error disappeared.

It seems that this commit fixed it:

(5) Question and Suggestion
Could you please update the luajit package used with the latest source code?

Thanks,
