What version are you trying to install in in? As Pharo 6 (and I believe the new 7) already have it installed- you can just select it in the Tools menu? If you are trying to upgrade it - there were some instructions in an email from Esteban - but you only need to do that if you want to run 64bit - otherwise you can stick with the stock Pharo 6 one?
There are known problems with iceberg in 64bit pharo6. If you don't yet need 64bit (and you probably don't) - I would say stick to 32bit and get more familiar with things. Soon there will be Pharo 6.1 and then you can upgrade if you need it.

32bits works fine. 64 bits needs to reinstall iceberg but works fine then. The 6.1 willmake that integration so 64 bits will be just fine
