I, too, have a lot of -dev packages installed for an on-device development. Amongst them, libc6-dev 2.5.1-1eglibc27+0m5+cssu2.1. IIRC, there were some challenges getting the right -dev packages. Build-essential is hopelessly outdated but, through some dependency mess, some -dev packages depend on it which means I ended up with some packages installed twice (for example, bimutils and binutils2.22).

It all happened months to years ago and I am afraid to touch this fragile castle of cards lest I break it as I do not quite remember how I achieved the current state. So I make a big backup before any major update, in case the update breaks it.

The upshot is, it IS possible to have -dev packages and the newest CSSU coexit happily. Just leave HAM behind and use FAM or, better still, apt-get to run the upgrade since getting any useful output from HAM is next to impossible. Pali is right, if you use -dev packages, then you should have at least some idea of how to use the command line tools.
