[RC3] the Sikuli IDE cann't Import xlrd or xlwt module

I tried it on this way(faq #2208).

When Sikuli IDE first starts, and then type "import xlrd/import xlwt" and run. It reports error lisk this.

But run again, Sikuli IDE doesn't report error.It works well.

Here are the versions I tried:
Sikuli 1.0rc3(930)
windows 7 64bit
xlrd-0.7.9
xlwt-1.0.0

I downloaded the Sikuli-1.1.0-20150914.231031-164 and tried to import xlwt or xlrd module, but has failed to import.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Any idea where I did wrong? Thanks!
