Forum OpenACS Q&A: compiling pthread.c for AOLServer getting error

I got AOLserver40.10 per instruction at
https://openacs.org/doc/current/aolserver4.html
and configured by
./configure --prefix=/usr/local/aolserver40r10 --with-tcl=/usr/lib
Then i typed make (i had to hack /usr/lib/tclConfig.sh
to change "tune" to "cpu" to compile further
but I think this is not related to the following problem)
now I get this problem:

Can anyone tell me how should i fix this "multiple def of _init" ?

thanks in advance!
