If the code in Petal.so uses any C library calls, it has to say so for 
Debian.  (Some OSes don't support this dependency information.)  The
library should be linked with whatever libraries it uses, probably by
adding `-lc' to the end of the link line.

ELF shared libraries could be loaded anywhere in memory, so the C code 
has to be compiled so that it doesn't depend on particular addresses
for code and data.  If it isn't, the code doesn't get shared between
multiple processes using it.

You need to add something like `-fPIC' to the compilation, e.g.

   gcc -O2 -c -fPIC foo.c
