Autoconf in Ubuntu

[newuse at qip.ru]

Hi all, it seems to be very old trouble, but I am not able to resolve it, I am regenerating src/modules/rlm_sql_mysql/configure  file by deleting  src/modules/rlm_sql/drivers/rlm_sql_mysql/configure and then regenerating configure file by  executing autoconf in  src/modules/rlm_sql/drivers/rlm_sql_mysql/ directory under Ubuntu 10.04, but configuration fails with  the following error:
[code]
=== configuring in ./drivers/rlm_sql_mysql (/home/alex/crsc/fr_server_2_1_x/src/modules/rlm_sql/./drivers/rlm_sql_mysql)
configure: running /bin/sh ./configure '--prefix=/usr/local'  '--enable-ltdl-install' --cache-file=/dev/null --srcdir=.
configure: WARNING: unrecognized options: --enable-ltdl-install
./configure: line 2802: syntax error near unexpected token `mysqlclient_r,'
./configure: line 2802: `	    FR_SMART_CHECK_LIB(mysqlclient_r, mysql_init)'
configure: error: ./configure failed for ./drivers/rlm_sql_mysql
configure: error: ./configure failed for src/modules/rlm_sql
 [code]

Could you please help me to resolve trouble, btw, in FreeBSD ports all is OK, I have tried to find a patch of configure.in in my FreeBSD system, but failed (I am new to programming)

I am using FR v2.1.x  branch

Best regards,
NewUse.
