Hi,
FYI, I just uploaded Dynare 4.5.0 (with a few additional patches taken from the 4.5 branch) to Debian unstable. It should hit mirrors soon.
I also updated the wiki page about Debian/Ubuntu packages. I realize that unofficial packages are now quite outdated. Do you plan to continue maintaining these? If yes, you could build upon the official package I just uploaded. I may help in the process if you want.
Best,
