Now that you are here, let me repost what I wrote earlier. I'll intend it all
by two spaces.

I still think that what you suggested is not all that appealing as a general
solution; you have a very particular local setup and maybe you will just have
to diver /usr/bin/install_name_tool.  I don't want to break the general OS X
setup for which this is part (and was added/suggested by Simon a while back).

  | Initial Comment:
  | I was unable to build Rcpp due to the fact that on my system I use
  | another compiler (it is installed from MacPorts in /opt/local/bin
  | area). The Rcpp/src/Makevars uses hard-coded path to /usr/bin/install_nam
  |  e_tool. This cause the linker to pick-up wrong install_name_tool which in my case should come from location of my compiler (i.e. /opt/local/bin). The error I got was the following:
  | 
  
  It would appear that you are referring to the last line of this section:
  
  $(USERLIB): 	$(OBJECTS)
  		$(SHLIB_CXXLD) -o $(USERLIB) $(OBJECTS) $(SHLIB_CXXLDFLAGS) $(ALL_LIBS)
  		@if test -e "/usr/bin/install_name_tool"; then /usr/bin/install_name_tool -id $(R_PACKAGE_DIR)/lib$(R_ARCH)/$(USERLIB) $(USERLIB); fi
  
  That line, if memory serves, suggested and provided by Simon for the OS X
  case.  It acts as both a test for OS X (as no other OS has
  /usr/bin/install_name_tool) as well as a use of the tool.
  
  What you suggest (ie remove the leading /usr/bin/) does not seem to
  work. Witness this:
  
  edd at max:~$ ls -l /usr/bin/install                            # I know I have thos
  -rwxr-xr-x 1 root root 113864 Nov 19 16:20 /usr/bin/install
  edd at max:~$ test -e install && echo "Found"                   # yet 'test -e' fails
  edd at max:~$ test -e /usr/bin/install && echo "Found"          # only full path works
  Found
  edd at max:~$
  
  With that I think your bug report is way too local.  I am sorry that your
  particular case is not covered by our installation, but I have not intention
  of breaking lots of working systems only to accomodate you.
  
  There may be other ways, and I am open to suggestions.  Maybe Simon can help
  once more.
  
  One idea would be 
  
  		@if test -e "/usr/bin/install_name_tool"; then install_name_tool -id $(R_PACKAGE_DIR)/lib$(R_ARCH)/$(USERLIB) $(USERLIB); fi
  
  which still has the explicit test with a path, but then calls without a
  path.  Or is that too fragile?
  
  Any help from OS X users appreciated 
  
  Dirk

  | To fix the problem I untar the source code, modified Rcpp/src/Makevars,
    replaced the path to install_name_tool, tar the package again and
    manually install it. Please review your test in Makevars and remove   hard-coded path to install_name_tool. It should be picked up from the environment.
