installing XML::Parser with cpan problem

when i try开发者_运维问答 to install XML::Parser with cpan i get following error

make[1]: *** No rule to make target `/usr/lib/perl5/CORE/thrdvar.h', needed by `Expat.o'.  Stop.
make[1]: Leaving directory `/root/.cpan/build/XML-Parser-2.41-c291nQ/Expat'
make: *** [subdirs] Error 2

does anyone know how to fix this? thanks in advance

This means that your Perl installation is incomplete. You'll need to install the Perl-devel package first before building any other perl modules.
