A lot of people have complained that they can't get dsniff to compile on FC2. I put up some very simple patches and instructions to get dsniff to compile on FC2 cleanly.
This assume you have Berkely db with 1.85 compatability enabled (full install of FC2 already has this).
If you use the exact versions with patches from this site, it should compile without any issues.

(Download patches or patched distros here. You must use exact versions specified here.)
This fixes the following errors:
