Do your homework and study all the information available on the Web:

Fink Web site
The Fink FAQ's
Fink User's Guide
Fink Usage
Official Apple's X11 FAQ
forums.macosxhints.com X11 FAQ

Read or search the Mailing Lists archives to check
if someone is having the same problem as you:

Fink archives:
1- At the Mail-archive.com:
Fink-beginners mailing list archive
Fink-users mailing list archive
(Search works, but the archives are a week behind)

2- At sourceforge:
Fink-beginners mailing list archive
Fink-users mailing list archive
(Small search field (poor) on the left hand side of the page)

3- The archives at GMANE.org work best for me:
Fink-beginners mailing list archive
Fink-general mailing list archive
Fink-devel mailing list archive

Apple's X11 archives:
Apple Mailing lists: X11 users
