I am not sure if I understand you correct: Northern Ireland is always 
correct (which means abbrevation is GBR) whereas Republic of Ireland is 
always incorrect (which means abbreveation is the value of 
--country-abbr). Did you mean that?

Anyhow you provided two error messages as examples. Both are located in 
the country Republic of Ireland.

[...,mkgmap:admin_level2=IRL,mkgmap:country=IRL]

The first way shows the problem very good. The mkgmap:admin_level2 tag 
is set to IE, so there must be a precompiled boundary with the tags 
admin_level=2 and nameXXX=IE where nameXXX is one of the tags set by 
name-tag-list. I have searched the precompiled bounds of Oct 16th (you 
are using them?) but I couldn't find such a boundary so far. So at the 
moment I have no idea about the problem...

I have downloaded the world_bounds_20111106.tar.gz. I do not have 
problems unpacking it. I have used 7-zip to create the tar.gz. Maybe 
that causes a problem?

Thanks, I will try that.
