Hi!
When compiling a program and linking it to graphviz libraries one need
to supply -L/usr/lib/graphviz and extend LD_LIBRARY_PATH with that
directory, otherwise linking and execution will fail.
Why are the libraries not stored in /usr/lib ?
Is that expected behaviour of the package?

They are stored in an unusual place to avoid any potential for namespace
collisions in /usr/lib
on 10 varieties of Unix.
LD_LIBRARY_PATH is not recommended as it is a royal-pain for the user.
Instead I recommend use of --rpath
Using pkgconfig you can set this up with:
CFLAGS=`pkg-config libgvc --cflags` -Wall -g -O2
LDFLAGS=-Wl,--rpath -Wl,`pkg-config libgvc --variable=libdir`
`pkg-config libgvc --libs`
