*** ExtUtils::AutoInstall configuration finished.

Configuring IBM Informix Database Driver for Perl DBI Version 2007.0914 (2007-09-14) (aka DBD::Informix)
You are using DBI version 1.601 and Perl version 5.008004
Remember to actually read the README file!

Perl: perl v5.008004 sun4-solaris-64int dl_dlopen.xs
System: sunos localhost 5.10 sun4u sparc SUNW,Ultra-2
*** Ideally, you should upgrade to Perl version 5.008008 or later.

Using INFORMIXDIR=/informix_10 and ESQL/C compiler esql
Using IBM Informix CSDK Version 2.90, IBM Informix-ESQL Version 2.90.UC3 from /informix_10
Note that bug RT#13708 (IBM CQ bug idsdb00139040) may affect you.
In particular, if test t/t93lvarchar.t detects problems, consider an
upgrade to CSDK 3.00 or later - it seems to be fixed there. All
other parts of DBD::Informix will probably work.

Beware: DBD::Informix is not yet aware of all the new IUS data types.

Assert macro will be disabled!
