dependens broken on pkg upgrade

[Slawa Olhovchenkov]

I am using custom repository, building by poudriere.
I am have instaled rrdtool.
rrdtool contains shared library
/usr/local/lib/perl5/site_perl/mach/5.18/auto/RRDs/RRDs.so

# ldd /usr/local/lib/perl5/site_perl/mach/5.18/auto/RRDs/RRDs.so
/usr/local/lib/perl5/site_perl/mach/5.18/auto/RRDs/RRDs.so:
[...]
        libicui18n.so.53 => not found (0)
        libicui18n.so.53 => not found (0)
        libicui18n.so.53 => not found (0)

# pkg info rrdtool
[...]
Shared Libs required:
        libpng15.so.15
        libintl.so.8
        libglib-2.0.so.0
        libgobject-2.0.so.0
        libpango-1.0.so.0
        libcairo.so.2
        libxml2.so.2
        libpangocairo-1.0.so.0
[...]

As result, after upgrading icu from 5.3 to 5.5 rrdtool is broken.
