gtk2+ not building

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

On i386-5.99.01, I'm unable to build gtk2+:

checking for C compiler default output file name... 
configure: error: in `/usr/pkgsrc/x11/gtk2/work/gtk+-2.14.4':
configure: error: C compiler cannot create executables
See `config.log' for more details.
*** Error code 77

config.log isn't helpful; it simply shows 'exit 77' as well.

Under the assumption that 77 was ENOLCK and that there was something
stale lying around, I rebooted, but it didn't help.
