exiv2 upgrade to 0.20 fails

[lyle2.0+macports@…]

Doing a "port upgrade outdated", I encounter an error upgrading exiv2. The relevant portion of the error log:

:msg:configure --->  Building exiv2¬

The error is similar to the one reported in #24820, and I attempted the same fix (sudo port -n upgrade --force libtool && sudo port clean exiv2), but to no avail.
