Hello, you can change two files. in file configure.py row 835 from lpatts = ["lib" + lib + ".*"] to lpatts = ["lib" + lib + "[0-9].*"] ( all my library call lib<*>4.a ) and file configure.py zeile 923 from check_license() to #check_license() You read Phil`s mail, that pyqt crash if you import QtCore. Now, you can only build pyqt on window's ;-).
