Of course, I'll be packaging Ruby 1.8.5 for iPAQ/linux as soon as it is released. Lightweight in my sense is smaller packages. I'll be using ruby, readline, irb and openssl only. I packaged network stuff separately in the past, but a PDA without network seems a bit useless. Oh, this will be unpacked onto jffs2, which is a compressed FS, so the actual flash-usage isn't much higher. ~/iPAQ/Ruby/ruby-1.8.5/ipkg$ wc *ipk 34 202 8344 erb1.8_1.8.5-preview3-1_arm.ipk 7 30 634 erb_1.8.5-preview3-1_arm.ipk 118 619 30304 irb1.8_1.8.5-preview3-1_arm.ipk 8 29 636 irb_1.8.5-preview3-1_arm.ipk 43 308 16210 ruby1.8-curses_1.8.5-preview3-1_arm.ipk 1387 8625 494482 ruby1.8-dev_1.8.5-preview3-1_arm.ipk 446 2429 115234 ruby1.8-doc_1.8.5-preview3-1_arm.ipk 231 1476 87676 ruby1.8-openssl_1.8.5-preview3-1_arm.ipk 22 150 7496 ruby1.8-readline_1.8.5-preview3-1_arm.ipk 305 1489 66108 ruby1.8-rexml_1.8.5-preview3-1_arm.ipk 109 594 25956 ruby1.8-rss_1.8.5-preview3-1_arm.ipk 14 79 2534 ruby1.8-runit_1.8.5-preview3-1_arm.ipk 192 1106 51064 ruby1.8-soap_1.8.5-preview3-1_arm.ipk 94 555 25262 ruby1.8-test_1.8.5-preview3-1_arm.ipk 139 762 33818 ruby1.8-webrick_1.8.5-preview3-1_arm.ipk 80 461 23358 ruby1.8-wsdl_1.8.5-preview3-1_arm.ipk 96 548 22922 ruby1.8-xmlrpc_1.8.5-preview3-1_arm.ipk 57 329 14210 ruby1.8-xsd_1.8.5-preview3-1_arm.ipk 75 353 15630 ruby1.8-yaml_1.8.5-preview3-1_arm.ipk 3048 18428 987842 ruby1.8_1.8.5-preview3-1_arm.ipk 7 32 648 ruby_1.8.5-preview3-1_arm.ipk 6512 38604 2030368 total
