libcomedi Linking problem

Dear Sirs,

    I have successfully installed a PCI 6036E
card at Slackware 9.1. I have tested it with
/testing programs and everything works OK!

I am using KDevelop 3.
When I run "my first Comedi program" i think I have
a problem linking the libcomedi libraries. Here are the
results of doing 'ls' at 2 of my directories:

/usr/local/lib# ls
libcomedi.a libcomedi.la* libcomedi.so_at_ libcomedi.so.0_at_ libcomedi.so.0.0.0*

and not at the /usr/lib/

root_at_patmos:~/Sources/comedilib-0.7.21/lib# ls -l libcomedi*.*
