>Description:
I've experienced a lot of problems with "make update" recently. The symptom
is always that a package which is rebuilt because one of its dependence
got updated fails to build during the "configure" stage. If I change to
that make directory and run "make clean" (just rerunning "make configure"
doesn't work) and "make" the build succeeds.

I think this problem is related to buildlink3 because things are missing
from the buildlink directories.

>How-To-Repeat:
I can reproduce the problem at least with these two sets of packages:
cd pkgsrc/math/fftw
make install && make clean clean-depends
cd ../../lang/f2c
make update

In this case "fftw" cannot be built because "f77" isn't found.

cd pkgsrc/sysutils/vcdimager-devel 
make install && make clean clean-depends
cd ../../misc/libcdio
make update

In this case "vcdimage-devel" cannot be build because the "libcdio" headers
cannot be found.

>Fix:
None provided.
