JDBC and Perl compiling problems w/ postgresql-7.1rc4

Hello there,

I first ran configure with the following options

./configure --with-perl --with-tcl --enable-odbc --with-java
--enable-syslog --enable-debug

and then compiled postgresql-7.1rc4 on Redhat 7.0 successfully
with the exceptions in JDBC and Perl modules as
indicated below.

I have both j2se version 1.3 and ant installed on the machine.

It seems like that the compiler does not like the fact that

/usr/lib/perl5/5.6.0/i386-linux/CORE/libperl.a

is not a shared object.

Your comments to resolve these issues is greatly
appreciated.

BTW, rserv module in contrib directory now compiles
beautifully.
