Error compiling mod_perl

[Sam Carleton]

This is the error message I got when I compiled mod_perl:

Perl lib version (5.00503) doesn't match executable version (5.006) at
/usr/lib/perl5/5.00503/i586-linux/Config.pm line 7.
Compilation failed in require at
/usr/lib/perl5/5.00503/ExtUtils/MakeMaker.pm line 13.

/usr/lib/perl5/5.00503/ExtUtils/MakeMaker.pm line 13.
Compilation failed in require.
BEGIN failed--compilation aborted.
make: *** [Version_check] Error 255

How do I fix this?
