I'm getting an error on trying to install my PyQt. I really don't know how to fix it. Wondering if anyone knows how to fix this error.

Running on:
Python 3.4
PyQt-gpl.5.4.1
sip-4.16.7
xcode 6.3.1

Undefined symbols for architecture x86_64:
"_PyUnicode_FromKindAndData", referenced from:
PyCustomWidgets::PyCustomWidgets(QObject*) in pluginloader.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [libpyqt5.dylib] Error 1
make: *** [sub-designer-make_first-ordered] Error 2


The last lines of command I ran on my terminal was this:

python configure.py --sip-incdir=$HOME/Downloads/sip-4.16.7/siplib INCPATH+=$HOME/Downloads/PyQt-mac-gpl-5.4.1/_qt --qmake ~/QT/5.4/clang_64/bin/qmake

followed by:

make


Anyone knows how to fix this?
