Инсталацията:

sudo perl -MCPAN -e 'install DBD::mysql'

Грешката:

dbdimp.c: In function 'mysql_dr_connect':
dbdimp.c:1677: error: 'ulong' undeclared (first use in this function)
dbdimp.c:1677: error: (Each undeclared identifier is reported only once
dbdimp.c:1677: error: for each function it appears in.)
dbdimp.c:1677: error: parse error before numeric constant
make: *** [dbdimp.o] Error 1

Решението:
Редактирайте ‘mysql_com.h’ в ‘/usr/local/mysql/includes’ и добавете:

typedef unsigned long ulong;
