shell failure on tools/wineinstall

Ran into this error after building wine again.  Not sure why I haven't seen
this before, but:

tools/wineinstall: line 272: [: too many arguments

which translates to this line:

      if [ ! `which wine` ]

On Solaris, if I do "which wine", I get a 
no wine in (long list of path entries)., so I assume another version
of "which" returns a blank string if wine doesn't exist?

Thoughts?
