This may only be related to 64-bit Gentoo but if you’re having build troubles try starting from scratch like this. Note: These are all commands that you’ll have to run directly. There is narrative except in step 6.
Step 2: tar xzvf libwiimote-0.4.tgz
Step 3: cd libwiimote-0.4
Step 4: autoconf
Step 5: ./configure
Step 6: Edit src/Makefile and add “CFLAGS=-fPIC” to it. If CFLAGS already exists just append “ -fPIC” to it.
Step 7: make
Step 8: make install
Now you’ll have libwiimote-0.4 built and installed. All you need are a few applications to take advantage of it. Stay tuned.
