dpkg -l sdl

nah, esdl…
ez már keményebb dió ^.^
a readme telepítésre vonatkozó része:

Compilation and Installation
=============================

You need erlang (http://www.erlang.org) version R9B.
You need libsdl (http://www.libsdl.org) (the development package) version > 1.2.5
You need opengl (with glu-1.2 (full version) libraries from your
                hardware manufacturer or a software version from http://www.mesa3d.org.

Precompiled versions are available for windows.

For unix like systems
Untar the esdl-VERSION.src.tar.gz and type ‘make; make install’
or put it anywhere and add the path in your ~/.erlang (C:/windows/.erlang) file

You might need to modify the c_src/Makefile to point out the correct paths
to header files and libraries.

To sucessfully build esdl you need complete GLU version 1.2 or later,
many linux system has a mesa-glu which don’t have the correct tesselation
routines, download the prebuilt sgi-version from http://www.mesa3d.org and click
on SGI-GLU link to find a rpm.

Install sdl so that the os can find the dynamic libraries:
On windows: put the .dll’s somewhere in your path or in $ESDL_PATH/priv
            (in the precompiled version (maybe old) SDL.dll is included)
On unix:    put the .so libs somewhere in your LD_LIBRARY_PATH

Testing esdl can be done by building the tests in the test directory and
running the test programs, example:
cd test
erl -pa ../ebin  (werl on windows)
Erlang (BEAM) emulator version 5.1.1 [threads:0]
Eshell V5.1.1  (abort with ^G)
1> testsprite:go().    %% Escape quits
2> testgl:go().
3> erldemo:go().
4> testaudio:go().
5> testjoy:go().

Note: Using esdl on nvidia cards and their drivers requires that erlang
was built with threads.
i.e. when building erlang do ./configure -enable-threads
otherwise erlang will crash with segfault

akkor mit is kellene csinálnom? make; make install…
aztán milyen LD_LIBRARY_PATH ba kell mit másolni?

pontositok.

most neked a /usr/lib-be kell a .so (shared object) fileokat bemasolni.
