DBD-Informix Installation

[weismat]

I am trying to install DBD::Informix DBD-Informix-2008.0513 with Active State Perl 5.8 under Solaris 10 and Informix 10. I have installed DBI 1.609 before. Both modules were taken straight from CPAN. I end up with the following compile error when running make.

Does anyone have an idea where am I stuck? I have put the full log into my scratch pad.
