[SOLVED] Examples wont' build on Ubuntu

Hello,

I am trying to build the examples on Ubuntu 11.04 but all I get from the Makefile is a bunch of errors:

./Makefile: line 18: datadir: command not found
sed: -e expression #1, char 14: unterminated `s' command

Is it possible to build those examples under Linux or the examples are meant to be built only on Win/VC++?

Thanks.
