You didn't say what the error is...

The fact -lgem appears twice ?
It is sometimes mandatory when libraries have interdependencies.
The important thing to understand is that the order of the libraries on 
the linker command line is significant: they are loaded from left to 
right. Normally, the most specific libs should appear first, then the 
most generic ones. If a library makes use of a previously used library, 
AND the required symbols have not been already satisfied, it is 
necessary to put the libraries on the command line once again to avoid 
unresolved externals.

The above example suggests that libgem has dependencies to libldg (which 
is quite improbable) and libldg has dependencies to libgem.

For information, ld has a special options --start-group and --end-group 
which can be abbreviated to -( and -)
Libraries listed between these options are searched repeatedly until no 
new undefined references are created. The documentation says this should 
be used only when unavoidable due to performance costs.

For example, the following options could do the trick here:
-( -lSDL  -lgem -lldg -)
