Posted on January 17, 2018 by jasiu

[Update]
Try to rebuild mapping util

# pkg which /usr/local/libexec/icon-name-mapping
/usr/local/libexec/icon-name-mapping was installed by package icon-naming-utils-0.8.90_1            
# portmaster -D icon-naming-utils

Just in case mount yours ports tree on /usr/ports


# mount -t nullfs /usr/jails/ports /usr/ports

Build and install package
