Here's the error message along with the last 30 lines of 'config.log': **** snippets **** checking whether to include zlib support... yes checking for gzgets in -lz... no configure: error: Zlib module requires zlib >= 1.0.9. <hostname> $ tail -30 config.log main () { /* Are we little or big endian?
