Overall looks good to me! A couple of comments: 59. (substitute* (filter file-exists? 60. '( 61. "ext/readline/readline.c" 62. )) Here we can assume that the file exists I believe, so the ‘filter’ call can be removed. 67. (substitute* (filter file-exists? 68. '( 69. "configure" 70. "configure.in" 71. "Makefile.in" 72. "ext/pty/pty.c" 73. "io.c" 74. "lib/mkmf.rb" 75. "process.c" 76. "test/rubygems/test_gem_ext_configure_builder.rb" 77. "test/rdoc/test_rdoc_parser.rb" 78. "test/ruby/test_rubyoptions.rb" 79. "test/ruby/test_process.rb" 80. "test/ruby/test_system.rb" 81. "tool/rbinstall.rb" 82. "tool/config.guess" 83. )) 84. (("/bin/sh") (which "sh")))) Likewise. In addition, I think only the .rb and .c files need to be patched, since the others are already handled automatically, normally. (In the future please send it as an in-line patch.) > I intend to patch rubygems so gems get installed in a $HOME dir > specifically named after the SHA.

It may be helpful to have a ‘ruby-build-system’, akin to ‘python-build-system’ but with the right incantations (info "(guix) Build Systems"). > Do we have a HOWTO on how to run expressions in the Guile debugger? > Never used that and would like to see how individual statements > evaluate in LISP. Basically there are two approaches.

Thanks Ludo and > others! I just wish I could use GUIX on servers where I don't have (and > won't get) root access. Or is there a way? With Nix I could run as a > normal user. It’s the same as Nix, which means that if the daemon cannot run as root, then it’s usable in a “degraded” mode (info "(guix) Build Environment Setup"). HTH, Ludo’.
