$ nm drv2-loader | grep pure
080485d0 T __pure_virtual
$ ./drv2-loader 
dlopen: ./drv2.so.6.0: undefined symbol: __pure_virtual

I really don't get it.  It should be resolved.  Let me check realplay.

$ nm `which realplay` | grep pure_virtual
nm: /usr/bin/X11/realplay: no symbols
$ nm -D `which realplay` | grep pure_virtual
0814b160 T __pure_virtual

Hm, so I have to mark it as dynamic somehow?  linker option... ah ha, ld 
option '-E'.  So I have to compile like so:

gcc -Wall -fPIC   -c -o drv2-loader.o drv2-loader.c
gcc -Wall -fPIC -Wl,-E -o drv2-loader drv2-loader.o -ldl

And then it loads.  :)  Okay, problem solved.
