If you set the likwid install path in config.mk and the last character is a slash, likwid-pin will not run with the following error message:
ERROR: ld.so: object '~/helper/likwid-2.2-inst' from LD_PRELOAD cannot be preloaded: ignored.
Delete the last slash and do
make clean && make && make install
and likwid-pin should work fine.
