I'm posting this for the benefit of anyone else encountering this thread (like me) and thinking Maple is a lost cause on newer kernels. We were bitten by this problem after upgrading our old RedHat 9-based infrastructure to a new Fedora Core 6-based one. As we are part of a site licence installation at a major university, I asked our site licensing officer to raise the issue with her contacts at MapleSoft. This was a week ago. I finally heard back from them and the good news is that they have now built an updated version of the maplelmg licence manager daemon. To use it, you need to be running a current (>= 9.5) version of the FlexLM -- now called Flexnet -- lmgrd daemon. (We happened to already be running the latest (10.8) version, but for anyone who's not, it is freely downloadable at http://www.macrovision.com/support/by_category/lmgrd.shtml). The new maplelmg works fine for us under Fedora Core 6 (though the workaround described elsewhere in this thread is still required to get the installer program to run). So, for anybody else having this problem: you can probably submit a support request to Maplesoft and ask them to send you the updated maplelmg. It does exist!
