mysql.h defines net_buffer_length in a conditional at line 327, 
#if !defined(MYSQL_CLIENT) && !defined(MYSQL_SERVER) 
&& !defined(EMBEDDED_LIBRARY) 
However either MYSQL_CLIENT or MYSQL_SERVER is guaranteed to be defined due to 
the statement at line 300, 
#if !defined(MYSQL_SERVER) && !defined(MYSQL_CLIENT) 
This means that net_buffer_length is never available to user programs which 
include mysql.h.  This problem is currently preventing me installing 
DBD::mysql with MySQL 4.1.2. 
This file was installed from the 4.1.2 RPMS on MySQL.com 

How to repeat:
Download current (MySQL 4.1-aware) DBD::mysql 2.9003 from CPAN 
perl Makefile.pl 
Compilation will abort with 
gcc -c -I/usr/lib/perl5/site_perl/5.6.1/i386-linux/auto/DBI 
-I/usr/include/mysql -mcpu=i486 -fno-strength-reduce -fno-strict-aliasing 
-I/usr/local/include -O2 -march=i386 -mcpu=i686   -DVERSION=\"2.9003\" 
-DXS_VERSION=\"2.9003\" -fPIC -I/usr/lib/perl5/5.6.1/i386-linux/CORE  mysql.c 
mysql.xs: In function `XS_DBD__mysql__GetInfo_dbd_mysql_get_info': 
mysql.xs:356: `net_buffer_length' undeclared (first use in this function) 
mysql.xs:356: (Each undeclared identifier is reported only once 
mysql.xs:356: for each function it appears in.)

Thank you for your bug report. This issue has been committed to our
source repository of that product and will be incorporated into the
next release.

If necessary, you can access the source repository and build the latest
available version, including the bugfix, yourself. More information 
about accessing the source trees is available at

Additional info:

Fix will be in 4.0.21 and 4.1.3

Note that 4.1.3 has a now prototype for mysql_shutdown(), which means that the current DBD::perl will not compile without adding SHUTDOWN_DEFAULT as a last argument to mysql_shutdown(). We will update DBD:MySQL regarding this as soon as possible.

I will take over this bug. I will test with latest code to verify the fix.

tested and verified that this does indeed work now with 4.0.21 and 4.1.3.
