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:
lanes.c: In function ‘LG_set_debug_threadname’:
lanes.c:1208:14: warning: variable ‘threadName’ set but not used 
[-Wunused-but-set-variable]
lanes.c: In function ‘LG_wakeup_conv’:
lanes.c:1918:12: warning: missing initializer [-Wmissing-field-initializers]
lanes.c:1918:12: warning: (near initialization for ‘tm.tm_min’) 
[-Wmissing-field-initializers]
threading.c: In function ‘THREAD_WAIT’:

tools.c:932:14: warning: comparison between signed and unsigned integer 
expressions [-Wsign-compare]
tools.c:945:14: warning: comparison between signed and unsigned integer 
expressions [-Wsign-compare]

... and an assertion failure during make test:
lua5.1: lanes.c:869: selfdestruct_remove: Assertion `found' failed.
Aborted (core dumped)

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 ***
