** PTHREAD SUPPORT MODE WARNING:

** create tcltklib library, this combination may cause memory trouble
** (e.g. "Hang-up" or "Segmentation Fault"). If you have no reason you
** must have to keep current pthread support status, we recommend you
** to make both or neither libraries to support pthread.
**
** If you want change the status of pthread support, please recompile
** Ruby without "--enable-pthread" configure option or recompile Tcl/Tk
** with "--enable-threads" configure option (if your Tcl/Tk is later
** than or equal to Tcl/Tk8.1).
