Allrighty, I employed some awk to get a good enough output:
----------------------------------------------------
#!/bin/sh
newline='\
'
pkg_info -as | \
tr '\n' ' ' | \
sed -e 's/Package Size://g' \
-e "s/(1K-blocks)/$newline/g" | \
tr ':' ' ' | \
awk '{print$4," ",$3}' | \
sort -gr | \
head -30
----------------------------------------------------
