I compiled and installed the lib as instructed by you and did a sudo ldconfig, still FS-UAE (2.5.5dev2) refuses to boot any ipf/raw images.
As you can see in this screenshot, the files are present in /usr/local/lib (path added to /etc/ld.so.conf)
Again you'll have to excuse my noob Linux ignorance.
I have attached the library if someone wants to have a look.
It's compiled in Mint 17 MATE x86.
