ffmpeg with mp3 support: How to install (use) in user mode?

view full story

http://unix.stackexchange.com – I want to use ffmpeg and libmp3lame on a stable Debian box. Alas, Debian does not support the libmp3lame package. So, I downloaded the sources for ffmpeg and the lame encoder, configured and installed them manually (on a testing machine). But I do not want to install ffmpeg and libmp3lame on the machine for all users (also because the built is not stable). I only want to use it for a single project with a single user. When I run ./ffmpeg/ffmpeg I get following error message: # cd ffmpeg # ./configure --enable-libmp3lame # make # ./ffmpeg ./ffmpeg: error while loading shared libraries: libmp (HowTos)
