Thanks, I tried to build luacheia5-5.0.0a1 and it broke twice.  The
1st I got past by changing RTLD_NOW to DL_LAZY, the only value
available in dlfcn.h and the one recommended by the man page for
dlopen() and friends, but I can't test the hack because of ...

... and so it gives up.  If you're interested I can send you all the
output from ./config etc. but I don't feel like I should send it to
the list unless asked.

It's frustrating because lua 5 works fine here and so do shared
libraries, but I haven't gotten them going together.

Thanks anyway,
Steve
