["N. A. Hilal" <wxascuivotrazxc@hotpop.com>]

 Dear all,
 
 I've tried to compile vpopmail on woody
 here is my configure option:
 
 ./configure --enable-clear-passwd=y \
 --enable-valias=y --enable-mysql=y  \
 --enable-libdir=/var/lib/mysql

but i got these error:

debroute:/usr/local/src/vpopmail-5.2.1# make
make  all-recursive
make[1]: Entering directory `/usr/local/src/vpopmail-5.2.1'
Making all in cdb
