BUG: libpng-1.2.10 port upgrade fails

[armando@…]

port -a upgrade is failing on libpng-1.2.10 for me (after a port sync and port selfupdate commands). Strangely, the error seems to be causing some sort of cyclical issue on one particular step of the build process, where it keeps trying to compile the shared library, but has missing symbols, and then tries again, just to fail again.

One iteration of this error looks like this:

---

Error: Unable to upgrade port: 1 ---> Building libpng with target all Error: Target com.apple.build returned: shell command "cd "/opt/local/var/db/dports/build/_opt_local_var_db_dports_sources_rsync.rsync.darwinports.org_dpupdate_dports_graphics_libpng/work/libpng-1.2.10" && make all" returned error 2 Command output: cc -dynamiclib \

... in the time it took to post this, about 5 minutes, the libpng port upgrade finally properly failed, with "Error: Unable to upgrade port: 1".

I can confirm this problem with a virgin install of darwinports on an intel powered mac.

A workaround is to add the file pnggccrd.o to the OBJS in the Makefile.

switched to ./configure-style build - should provide mxx-support & do compile
