Hi,

Thank you, this works partially (configure detects the right version)
but it now fails in the final link stage:
[...]
-R/usr/pkg/lib -Wl,-rpath,/usr/pkg/lib -L/usr/local/lib -L/usr/lib  -lz
-L/usr/local/lib -Wl,-rpath,/usr/local/lib -lSDL -lpthread -lcurses
initc.o(.text+0x15f0): In function `SplitSetup':
: undefined reference to `gzdirect'
initc.o(.text+0x18e3): In function `SplitSetup':
: undefined reference to `gzdirect'
initc.o(.text+0x1b64): In function `SplitSupport':
: undefined reference to `gzdirect'
initc.o(.text+0x23e6): In function `loadROM':
: undefined reference to `gzdirect'
initc.o(.text+0x6094): In function `loadGZipFile':
: undefined reference to `gzdirect'

These symbols are found in the pkgsrc version but not in the /usr/lib
version. Should I try moving the -lz around so it comes before
-L/usr/lib?

Configure also isn't detecting libpng in /usr/pkg even with the
environment variables and --with-libpng-prefix=/usr/pkg

The software is zsnes which is actually already in pkgsrc: older
version, ~50 dependencies, I only need about 4-5 features (maybe more
customizations optioins are needed?).
