Hello,

I'm running 4.4-STABLE and am having problems with the gv port not 
working.  I've just deleted the port and reinstalled it, and am now
running gv-3.5.8.

make install works.

However when trying to view a postscript file I get the following error 
message from the gv X binary:

GhostScript Messages

/usr/libexec/ld-elf.so.1: Shared object "libpng.so.4" not found

Error: Postscript interpreter failed in main window.

I note that I have the port png-1.2.0 (Library for manipulating PNG
images) installed and the ports packing list shows that it provides
/usr/local/lib/libpng.so.5, not ".4".

As I don't have a /usr/local/lib/libpng.so.4 library I am unsure why gv 
has tried to link against this version, as consequently doesn't work, when 
if it linked against libpng.so.5 everything would be working fine.

I also note that ldd /usr/X11R6/bin/gv doesn't depend on the library 
directly, so perhaps the problem is that one of the libraries that it 
links against in turns requires libpng.so.4

[sjmudd@unicorn postfix-temp]$ ldd /usr/X11R6/bin/gv
/usr/X11R6/bin/gv:
        libm.so.2 => /usr/lib/libm.so.2 (0x2809d000)
        libXaw3d.so.7 => /usr/X11R6/lib/libXaw3d.so.7 (0x280b9000)
        libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x2810c000)

        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x28198000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x281a6000)
        libc.so.4 => /usr/lib/libc.so.4 (0x28280000)
        libXThrStub.so.6 => /usr/X11R6/lib/libXThrStub.so.6 (0x28319000)

How can I tell which library is out of date (if this is the case) and 
rebuild it accordingly?

Is this something I should reports to freebsd-ports or am I doing 
something wrong somewhere?

Thanks for any pointers.

Regards,

Simon
