[Ipopt] Matlab Build with -framework Accelerate

[Marco Rozgic]

That is what I essentially did. I just wanted to post out the problem that was already addressed by Ted.
It's great that Ipopt has such a good crowd taking care of business.

Best,

I would guess that re-running autoconf on all dependencies to produce new configure scripts would  fix the issue. We'll try to do this as quickly as possible. I believe a new stable version of Ipopt is also in the works and that should be available within about 2 weeks, but Stefan can confirm this.

However, afterwards I was trying to build a mex file that incorporates the MacOS blas and lapack, wich are now given by the framework Accelerate and not anymore by the vecLib framework. I used the configure site script and added the following to the configure command:
