The correct commandline switch is -pthread (no l, see 'man gcc'). This takes care of preprocessor *and* linker settings.

The luarocks build of lanes on my Ubuntu 11.10 is broken as well. Compiling manually (using -pthread in CFLAGS and LIBS and replacing -Werror with -Wextra) gives some warnings:

This is for the source rock from the luarocks repository. A current download from github gives some more warnings and no assertion failure during 'make test', but it freezes instead: *** glibc detected *** /usr/bin/lua5.1: double free or corruption (!prev): 0x096eaab8 ***
