Hi. Does anyone have any advice for dealing with a messed up pkgsrc? 
While most applications work fine, I appear to have a deeply buried 
dependency on an out-of-date package that keeps gphoto2 from building, 
gnucash from running, and mozilla from displaying file dialogs properly 
(strange characters appear instead of filenames). I'm tempted to just 
delete every package and start from scratch, but don't want to take the 
system down for that much compilation. I've used "make update" on all 
three misbehaving apps. The only clues that I've come across are that 
gnucash's problems appear to be in a library provided by g-wrap, and 
gphoto2's problem appears to be in libcdk (provided by cdk). Oh, and 
gnucash keeps giving warnings about moved libraries during the build 
process.

My best guess is that I have some obsolete libraries lying around that 
are being used instead of their newer versions.

Any suggestions? I'm running NetBSD 1.5.2 on i386.
