=begin Hey all, Code some code here that --works–, only that running it with the debug option throws up some errors. I’ understand that net/ssh requires openssl, which I have built, but maybe it’s in a non-standard location. Can anyone throw some light on this? gem list --local \*\*\* LOCAL GEMS \*\*\* needle (1.3.0) Needle is a Dependency Injection/Inversion of Control container for Ruby. It supports both type-2 (setter) and type-3 (constructor) injection. It takes advantage of the dynamic nature of Ruby to provide a rich and flexible approach to injecting dependencies. net-ssh (1.1.2) Net::SSH is a pure-Ruby implementation of the SSH2 client protocol. sources (0.0.1) This package provides download sources for remote gem installation I have built the openssl with `make && make install`, no other options. ls ~/proj/build/packages/openssl-snapshot-20040726/ dep openssl\_missing.c ossl\_bn.c ossl\_config.h ossl\_hmac.c ossl\_pkcs12.c ossl\_pkey\_dsa.c ossl\_ssl.h ossl\_x509ext.c ruby\_missing.h extconf.rb openssl\_missing.h ossl\_bn.h ossl\_digest.c ossl\_hmac.h ossl\_pkcs12.h ossl\_pkey.h ossl\_version.h ossl\_x509.h GNUmakefile ossl\_asn1.c ossl.c ossl\_digest.h ossl\_ns\_spki.c ossl\_pkcs7.c ossl\_pkey\_rsa.c ossl\_x509attr.c ossl\_x509name.c lib ossl\_asn1.h ossl\_cipher.c ossl\_engine.c ossl\_ns\_spki.h ossl\_pkcs7.h ossl\_rand.c ossl\_x509.c ossl\_x509req.c Makefile ossl\_bio.c ossl\_cipher.h ossl\_engine.h ossl\_ocsp.c ossl\_pkey.c ossl\_rand.h ossl\_x509cert.c ossl\_x509revoked.c MANIFEST ossl\_bio.h ossl\_config.c ossl.h ossl\_ocsp.h ossl\_pkey\_dh.c ossl\_ssl.c ossl\_x509crl.c ossl\_x509store.c Here’s the code.

So no need to worry.
