Bug ID: 268514
Summary: graphics/png: missing symbol after upgrading from
1.6.37 to 1.6.38
Product: Ports & Packages
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: Individual Port(s)

After upgrading to libpng 1.6.38 through the ports framework all ports using
libpng are broken. The error is:
/usr/local/lib/libpng16.so.16: version PNG16_0 required by /usr/local/bin/xv
not defined
Downgrading to 1.6.37 restores a working state. It seems this error is due to
the switch to cmake as build system. Using autoconf to build 1.6.38 results in
a package that can be used to upgrade the installed version and ports using
libpng keep working, eg. xv.
Looking at the symbol table of libpng16.so shows that all exported png_ symbols
lack the @@PNG16_0 suffix that is used with an autoconf build. The update to
1.6.39 does not fix this issue.
