Thx, Mr. Voelker! :) Thanks to your answer, I was able to install with:
sudo gem install dm-sqlite-adapter I'm not sure, but I believe the key was installing the full Xcode, not just the "Command Line Tools" (which I did before). *THE LUCKY STEPS TO SUCCESS I MADE* For others, who also run into this problem I did the following steps: 1. Installed the latest Xcode 4.6 (Jan, 28th) from https://connect.apple.com 2. Uninstalled my already (via MacPorts) installed version of "sqlite" using "port uninstall sqlite" *(not necessary, if you didn't install it in the first place)* 3. Did a cleanup of my already installed Homebrew version using "brew cleanup" 1. To be precise I used this line "rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup" but received the following error caused by the part before "&&": *"Error: No such file or directory - /usr/local/Cellar"* 4. Installed sqlite with Homebrew using "brew install sqlite" 1. And yes, I received the warning: *"Warning: It appears you have MacPorts or Fink installed. Software installed with other package managers causes known problems for Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again."* — but I ignored it. 2. Received this second warning: *"Warning: This keg was marked linked already, continuing anyway Warning: Could not link sqlite. Unlinking... Error: The `brew link` step did not complete successfully The formula built, but is not symlinked into /usr/local You can try again using `brew link sqlite'"* 3. So I tried "brew link sqlite" which resulted in: *"Linking /usr/local/Cellar/sqlite/3.7.14... Warning: Could not link sqlite. Unlinking... Error: Could not symlink file: /usr/local/Cellar/sqlite/3.7.14/bin/sqlite3 Target /usr/local/bin/sqlite3 already exists. You may need to delete it. To force the link and delete this file, do: brew link -f formula_name To list all files that would be deleted: brew link -n formula_name"* 4. So, I ignored this error as well and typed "sudo gem install dm-sqlite-adapter" which ran successfully! :) Pretty long journey, but worth it, I guess! ;) Best regards, - Alex On Thursday, January 31, 2013 3:05:21 PM UTC+1, Abe Voelker wrote: > > The gem needs the SQLite development headers in order to compile native > code.
