- From the Maxima website I understand that CMUCL is the fastest option for Maxima. SBCL is a fork of CMUCL and is currently the most popular, best supported and has the fastest development of all free Common Lisp implementation that I know of. I say that mostly to contrast SBCL with GCL which at times appears completely dead upstream. Due to GCL's inactivity and lack of use and development it has a lot of problems which I have no time to solve. Masking and possible removal of GCL has been something which has been on the table for a long time[1] but which I have been reluctant to actually do. I would prefer not to get rid of GCL but for now to discourage its use and prepare for a possible removal I have masked it. Upstream seems to be working on a release at a snail's pace and looks to be in the final phases of preparing for a release but still it might take them many months. Depending on what actually happens GCL may be removed (possibly temporarily). Anyway, you have two options: 1) Try SBCL. 2) Unmask GCL.

You need to put "dev-lisp/gcl" in /etc/portage/package.unmask and also "dev-lisp/maxima -gcl" in /etc/portage/package.use.mask to undo my recent masks.

Well, as I explained gcl upstream could really use your help. I am happy to keep experimental gcl ebuilds in the lisp overlay.

Thanks for speaking up. It is always good to hear from users. Marijn [1]: - -- If you cannot read my mind, then listen to what I say.
