Just for the records, this libc was bump up at the H2K9, witch is 
totally fine for sure and I have no issue or complains about it.

Log entry is clear about it

"Bump the libc major for the post-h2k9 string of ABI changes and 
additions (rthreads, MB_LEN_MAX, rdomains)"

and is also available here:

http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/shlib_version.diff?r1=1.119;r2=1.12...

I am only wonder if when this happened if the various packages that 
depend on them for example are redone. I know there was cut back in the 
pass as well for lack of men power for this.

Again not a complain what so ever. I just wanted to know if the built 
system actually redo them when this happened or not and only packages 
are rebuilt only when they are change themselves.

Sorry for the noise, just wanted to know for my own knowledge and I am 
fine redoing it from port, but I prefer use packages when available, 
thats' all.

Obviously the package now wants to use libc.so.52.0 witch is not present 
in a fresh new snapshots install as only the libc.so.53.0 is now, but 
would be present on an upgrade snapshots. I sure can copy over the 
libc.so.52.0 and be done with it.

My question was only in regards to packages rebuilt when this situation 
happened nothing more nothing less.

Sorry for the noise.

Best,

Daniel
