PL/Perl compilation error

Hi,

I have just installed Perl 5.6.0 and PostgreSQL 7.0.2. After successfull installation of both these
programs I tried to make PL/Perl support. After running the commands from Postgres manual I have
received the following errors


[root@eaccess plperl]# perl Makefile.PL

What I'm doing wrong?
