[Gnuplot-bugs] [patch/configure.in] Check for lua.pc *and* lua5.1.pc

[Daniel L. <dan...@gm...>]

Hi,

On Debian and Ubuntu systems (and probably more) there is no pkg-config
file lua.pc but there is a lua5.1.pc. I've attached a patch to fix the
detection of lua via pkg-config. The patch was made against CVS and
tested on my system.

Regards, Daniel
