luarocks on 64 bit linux

[Phoenix Sol <phoenix@...>]

Can anyone please explain what this symptom indicates:

( Linux 2.6.18.8-x86_64 SMP )

#luarocks install kepler

Installing http://luarocks.luaforge.net/rocks/kepler-1.1.1-1.src.rock...

Archive:  /tmp/luarocks-rock-kepler-1.1.1-1-7924/kepler-1.1.1-1.src.rock
  inflating: kepler-1.1.1-1.rockspec  
  inflating: kepler-1.1.1.tar.gz     

Error: /tmp/kepler-1.1.1-1-9880/kepler-1.1.1-1.rockspec: Unknown field hooks
 ( ...googling "unknown field hooks" fetches nothing relevant )

Besides that, I have noticed some rock install attempts fail like this:

#luarocks install md5
...
/usr/bin/ld: src/md5.o: relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC
src/md5.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [src/core.so] Error 1

Is there a trick to using luarocks on this platform?  ( I installed it with 'apt-get install luarocks'... )

Should I just forget luarocks and install everything manually?

Thanks!!
