Hi,

I have now uninstalled it and installed the ELPA version and it worked out of the box…

I have some colleagues that also had troubles installing auctex on a Mac this summer (I was not involved in the installation but the installation script that pulls it from git and places in site-lisp comes from the same source) so I cannot say that he had the same problem.

This is just for my curiosity and education. The answer is probably out there but I am not sufficiently knowledgeable about ELPA to find the answer… No need to answer if you don’t have time...
How does emacs generate the search path to ELPA? Is the search path ~/emacs.d/elpa/ hardcoded into Emacs? I have not added anything to my .emacs but it finds auctex without my intervention…

My load path now has the following entries: "/Users/larer/.emacs.d/elpa/auctex-11.89.6/" "/Users/larer/.emacs.d/elpa/auctex-11.89.6” as a followup should there be two, one with trailing slash and one without?

Thanks for your efforts! They are really appreciated

Best,
Lars
