*****Installing Dynamips*******

I had a couple of problems to making dynamips work, i found several methods,
1- one is how they describe it, by installing dynagen and using its dynamips, run
>"sudo /Application/Dynagen/dynamips -H 7200"
on terminal, to run has root.(after open GNS3.app, if u want to open GNS3 has root, run in terminal
>"sudo open /Application/GNS3.app/Content/MacOS/GNS3" )

2-Install macports and after install dynamips-devel and use this has your dynamips(in GNS3 you need to link it has your dynamips path you should find it with >"port contents dynamips-devel"

3- or download dynamips Dynamips 0.2.8-RC2 for Mac OSX copy to /Application/GNS3.app/Content/Resources/ give it root rights
>"chmod 777 /Application/GNS3.app/Content/Resources/dynamips-0.2.8-RC2-OSX-Leopard.intel.bin" and
>"chown root:wheel "/Application/GNS3.app/Content/Resources/dynamips-0.2.8-RC2-OSX-Leopard.intel.bin"

i hope this helps, if it is a little messy and someone doesnt understand i will try to explain or help any way i can, ty! :)
