No dice. Here's the relevant section from make, which appears to be unable to find zlib: compiling zlib make[1]: Entering directory `/root/ruby-1.8.4/ext/zlib' make[1]: Nothing to be done for `all'. make[1]: Leaving directory `/root/ruby-1.8.4/ext/zlib' making ruby From what I can tell, zlib lives at /usr/lib/ libz.so libz.so.1 libz.so.1.2.1.1 libzzip-0.so.10 libzzip-0.so.10.0.82 libzzip.a libzzip.la libzzip.so as well as /lib/uncompress.o usr/include/zconf.h usr/include/zlib.h ... but it appears ruby's make isn't seeing any of that. I am going to check the rubygems docs (sparse IIRC). rt -- Posted via http://www.ruby-forum.com/.
