Freedom:~ peterhin$ ls -a
.
..
.CFUserTextEncoding
.DS_Store
.Trash
.Xauthority
.Xcode
.adobe
.bash_history
.citrix
.cups
.dvdcss
.fontconfig
.lesshst
.macports
.profile
.profile.macports-saved_2009-09-28_at_09:30:38
.profile.save
.viminfo
CTX.DAT
Desktop
Documents
Downloads
Library
LimeWire

WLink
mbox
–p

So If I understand correctly I should delete the .profile.save and  
place the  "export HISTCONTROL=ignoredups" in the .profile and all  
should work.
