You will need to provide config.log in order to have it investigated. I can confirm mpc-1.2.0 builds fine with mprf-4.1.0.
Thank you for the report. We need to have all information at hand before ticket assignment. That is why I ask you to * attach the logs as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket Please reopen this ticket (Status:UNCONFIRMED) afterwards.
Sorry for that false alarm. I found mpfr.h in my /usr/local/include/. Somehow it get there a year ago according to creation time. May be some experiments. After deletion emerge works fine.
