tk required for rebuilding X11 port ?n

[dreamwvr <dreamwvr_(_at_)_dreamwvr_(_dot_)_com>]

hi,
  Am ccing misc in case this is not the appropiate list. thanks.. Anyhow 
decided to install X in OBSD to check it out (Usually never use X on OBSD 
sys but thought i would go for the full meal deal and live a little.:-))
Was applying the patches including the huge one as quoted on errata the patch
hunks apply just  fine.  But when compiling the X11 tree i get a error that Tk
gt or eq to  4.1 is required. Whereas i just installed tk 8.0.5 from ports.
Which toolkit will work? So that X11 source branch plays nice with the 
tk just installed? 
					TIA
