Comment:

 Excuse me! On my PowerBook MacPorts was able to use lbzip2 to decompress a
 source tarball, but when MacPorts tried to use lbzip2 to compress an
 archive, it failed for me as it did for you:
 {{{
 lbzip2: WORKER-THREADS not set, specify "-h" for help
 }}}
 According to
 [https://github.com/kjn/lbzip2/blob/8702655221f8e9cd488beb9572294baa734d2d09/src/main.c#L613-L624
 the source code], this message is only emitted if `_SC_NPROCESSORS_ONLN`
 is not defined, which is indeed the case on Tiger; it was introduced in
 Leopard.

 MacPorts legacy support has an implementation of `sysconf` that supports
 `_SC_NPROCESSORS_ONLN`  on Tiger, and including that in the port fixes it
 for me, so I'll commit that along with the required revbump shortly.
