Since the latest update, mail/mutt fails to build on NetBSD 7.0.1:

configure:
***
*** It is now required to build with support for the
*** New Portable Threads Library (nPth). Please install this
*** library first.  The library is for example available at
***   https://gnupg.org/ftp/gcrypt/npth/
*** (at least version 1.2 (API 1) is required).
***
configure: error: 
***
*** Required libraries not found. Please consult the above messages
*** and install them before running configure again.
***


Adding

.include "../../devel/npth/buildlink3.mk"

to Makefile didn't change the situation.
