"libicuuc.so.61" not found, required by "libephymisc.so" on RPi2

[bob prohaska]

Can anybody tell me how to fix an error reported by www/epiphany on an RPi2,
"libicuuc.so.61" not found, required by "libephymisc.so" with the system
at 11.2-STABLE #2 r345473 and ports at 498696 ?

Both epiphany and icu are up to date, there was no deliberate deletion
of old libraries but apparently it happened anyway.

Thank for reading, and any guidance!
