---------------------------------+------------------------------------------
 I'd expect symlinks to be created with the program-suffix.  Instead what
 happens is that cabal-install correctly suffixes the installed binary, but
 attempts to create a symlink to it from an unsuffixed name, which can fail
 if the unsuffixed name already exists in the symlink-bindir.

 {{{
 ~ $ cabal --version
 cabal-install version 0.13.3
 using version 1.14.0 of the Cabal library
 }}}

 Example:

 {{{
 gruff $ cabal install --program-suffix=-fixed
 ...[snip]...
 Warning: could not create a symlink in /home/claude/opt/bin for gruff
 because
 the file exists there already but is not managed by cabal. You can create
 a
 symlink for this executable manually if you wish. The executable file has
 been
 installed at /home/claude/.cabal/bin/gruff-fixed
 }}}

 (The symlink already existed in this particular case, because I wanted to
 install my development program with a suffix to avoid clobbering the known
 working version.)
