Is a parallel build of Maxima (using make -j N), OK?

Yes, the Lisp compilation takes a long time, but so does Maxima too. If it was 
possible to reduce this somewhat, it would be good.

However, building and installing in parallel using

./configure --some options

$MAKE

$MAKE install

has failed once during the install phase. Below is the log. It was actually done 
as part of a build of Sage, but the commands above are what were typed. It looks 
like a directory was made, then tried to be made again, so mkdir exited with an 
error.


It *may* be possible to do a parallel build, but not a parallel install. But I'm 
not going to waste much time on this.
