Compilation problem

Hello everybody,

I'm new to Ion (at least, trying to be), and far from an expert in many
domains regarding Linux... but I want to try Iont. In particular, I'm not
familiar with compilation of sources, most of the time yum do the work I
need, and for the rest "./configure;make;make install" is successful most of
the time.
But with Ion, I have a problem, it seems with lua dependency, as far as I
understand.
For information, I'm using Fedora Core 9, have install Lua using yum.
When I send the make command, it failed. Here is the output (the first few
lines, surely enough):
>

Before, I have install both lua and lua sources (using yum). I've tried to
change the path to lua in the system.mk file (LUA_DIR=/usr), but it does not
change anything.

Can anyone help me to solve this issue?

Best regards,
