Yes Chris, you are right, I did not mention that, this adds the correct
-lpthread option to the link statement, and should solve the problem
hereunder.
However, the
export CFLAGS="-DUSE_PTHREAD"
statement is necessary for me, before running the ./configure ... ,
otherwise, it will compile with the forked option, as the USE_PTHREAD
flag stays unset.
