I'm trying to see if I can get anywhere with compiling Prospector on Linux, using a Xubuntu x86-64 box.
So far, I've pulled the SVN source from the repo, and have installed FreeBASIC and verified that I can compile and run some example programs.
I'm now looking at FreeBASIC-ext/fb-extended-lib. It doesn't appear to have an updated official Linux version, so I'm probably going to have to compile that from source too (ugh).
I'm a bit concerned that even if I can get it working, it will still be impossible to run on other Linux machines unless the user installs a bunch of extra packages. Maybe I'll at least be able to document a method for other people to build their own binaries, though.
