I am trying to check for the files, but I can't get it to work right.

Any ideas?

Here is what I am trying:

@@ -207,6 +207,30 @@
 .    endif
 .  endfor
 .endfor	_TOOLS
+#
+# Check if tools exist.
+#
+# todo: get rid of space and arguments too before checking

+.  for _tool_ in ${USE_GNU_TOOLS}
+_tool_filename_:=	${${_tool_:tu}}
+_found_=	NO
+.    if !empty(_tool_filename_:M/*)
+.      for _dir_ in ${PATH:C/\:/ /g}
+.        if exists(${_dir_}/${_tool_filename_})
+_found_=	YES
+.        endif
+.      endfor
+.    else
+.      if exists(${_tool_filename_})
+_found_=	YES
+.      endif
+.    endif
+.    if (${_found_} == "NO")
+_TOOLS_NEED_GNU.${_tool_}=	YES
+_TOOLS_REPLACE.${_tool_}=	NO
+.    endif
+.  endfor

 .if ${_TOOLS_REPLACE.awk} == "YES"
 _TOOLS_OVERRIDE.awk=	YES
