List-Unsubscribe: , List-Archive: Hi. Got all the binaries for ghostscript, however getting undefined-symbol-type errors in libpng. Every time I run ghostscript I get: Error in loading shared libraries: libpng.so.3: undefined symbol _dso_handle. This also happens when I try to run hpijs. Also, I attempted to compile a2ps, but got errors related to a missing /usr/local/a2ps-4.13/runrunflex. I checked the web page, but didn't find any references to dependencies. Any ideas as to why this may be happening? Thanks!
