Created attachment 203838 [details] svn-diff-rubygem-bdb1 unbreak with ruby-2.5. same error as in bug #237410.
Overlooked: There are no ports dependent upon this port It is the question if we still need this port.
You can mark the port as deprecated and to be removed till end of month or next month. If I check INDEX-12 file, port is not used by any other port.
Created attachment 203852 [details] svn-diff-rubygem-bdb1_v2 Set expiration date to 2019-04-30.
Fixed with ports r500313.
