>dnl check for dynamic linking functions
AC_CHECK_LIB(dl,dlopen)

dnl check for the libdbi library
AC_CHECK_LIB(dbi,dbi_initialize)

dnl to check for the availability and function of a particular
dnl driver we need a runtime check (since the driver is loaded
dnl dynamically). This example checks for the mysql driver
AC_MSG_CHECKING("for libdbi mysql driver (dynamic load)")
AC_RUN_IFELSE(
