>Description:
After building digest from pkgsrc-current, the package can't be installed 
because

# pkg_add  /home/pkgsrc/packages/pkgtools/digest-20121220.tgz                   
                                  
pkg_add: Warning: package `digest-20121220' was built for a platform:
pkg_add: NetBSD/earmhf 6.99.24 (pkg) vs. NetBSD/earm 6.99.24 (this host)
pkg_add: 1 package addition failed

The binary itself works, and all values indicate that I did actually install 
earmhf, not earm.

In fact, pkg_add is an earmhf binary too:
# readelf -n /usr/sbin/pkg_add
