Installing mysql 5 with linuxthreads from ports

[Valerio daelli]

Hi
I have problem installing mysql 50 on FreeBSD 5.4.
I am trying to install it with linuxthreads and I keep getting these
errors:

$ cd /usr/ports/databases/mysql50-server

$ make -DWITH_LINUXTHREADS -DDATA_DIR=/data/mysql
CONFIGURE_ARGS="--without-debug --without-readline \
                        --without-libedit --without-bench
--without-extra-tools \
                        --with-libwrap --with-mysqlfs --with-vio
--with-low-memory \
                        --enable-thread-safe-client --enable-assembler
--without-berkeley-db \
                        --with-named-thread-libs=-pthread
--prefix=/usr/local" install

.....

Stop in /usr/ports/databases/mysql50-server/work/mysql-5.0.16/sql.

I found the definition of the function pthread_setprio in
/usr/local/include/mysql/my_pthread.h.
Does anybody how to fix this error?
Thanks
