The basename command gets expanded by the shell you use *BEFORE* find
has a change to run.

You can try playing tricks with escaping the backquotes, which is
probably going to result very quickly in ugliness like \\\`foo\\\` or
you can use find to "generate" a list of filenames which will be
"processed" by the rest of the command-line to spit out the rename
commands, and feed them to sh(1) for execution, i.e.:

    $ ls -l
    total 0
    -rw-rw-r--  1 keramida  wheel  - 0 Aug 31 18:33 koko.dist
    -rw-rw-r--  1 keramida  wheel  - 0 Aug 31 18:33 lala.dist

    $ find . -name \*.dist | \
      awk '{ printf "mv \"%s\" `basename \"%s\" .dist`\n",$0,$0; }'

    mv "./lala.dist" `basename "./lala.dist" .dist`
    mv "./koko.dist" `basename "./koko.dist" .dist`

    $ find . -name \*.dist | \
      awk '{ printf "mv \"%s\" `basename \"%s\" .dist`\n",$0,$0; }' | sh

    $ ls -l
    total 0
    -rw-rw-r--  1 keramida  wheel  - 0 Aug 31 18:33 koko
    -rw-rw-r--  1 keramida  wheel  - 0 Aug 31 18:33 lala
