   I just tested it with the trunk Boost Build version and on Windows 
under both cmd.exe and cygwin's bash shell it places the installed 
target under the current folder.

   Workaround that should work on all platforms should be:

path-constant INSTALL_PATH : /speedo ;
install speedoInstall : speedoclt : <location>$(INSTALL_PATH)/bin ;

   There are several factors affecting this:

   1. Path constants are always in platform native format, i.e. your 
INSTALL_PATH variable holds the value '\speedo' instead of '/speedo'.
   2. Install rule uses its name as its target location in case no 
target location is explicitly specified using the <location> option.
   3. Something silently trims '\' characters from target names.

   I'll look some more into why '\' characters get trimmed but this 
should be enough to solve your problem.
