In recent 11.25 cPanel builds, MAIL::SPF refuses to build resulting in error messages mailed by cPanel to the administrator and the possibility of SPF-related cPanel functions being broken. There is a simple fix for this for the time being until it is fixed upstream in CPAN:

# perl -MCPAN -e "get('Mail::SPF')"
# cd /home/.cpan/sources/authors/id/J/JM/JMEHNLE/mail-spf
# tar -xzvf Mail-SPF-v2.007.tar.gz
# cd Mail-SPF-v2.007
# perl Build.PL
# ./Build
# ./Build test
# ./Build install
# /scripts/checkperlmodules --full
