<div><br></div><div>Incidentally you complain about ECL's long build time, but parallel build will NOT help you. Since in Sage you already use a previously built GMP library (or whatever variant) the largest chunk of time is spent in running ECL's compiler, a process that CAN NOT be parallelized, due to delicate dependencies in bootstrapping code.</div>
<div><br></div><div>In any case I am surprised to read that ECL's build time is the bottleneck. On my laptop it takes just 1+2 minutes to build it and it is a slow OS X machine (32 bits). What build flags are you using?</div>
