CentOSでgitのproxy越えにハマる

githubなんかからgitのレポジトリを落とそうとすると，https://とgit://がありますが，httpのプロクシしか立っていないためにhttps://で落とそうとしてもエラーになりました．

> git clone https://github.com/imatix/zguide.git
Cloning into zguide...
fatal: Unable to find remote helper for 'https'
> setenv https_proxy http://proxy
> git clone https://github.com/imatix/zguide.git
Cloning into zguide...
fatal: Unable to find remote helper for 'https'

どうもプロクシ以前の問題の気がするので調べると，INSTALLファイルにこんな記述が．

- "libcurl" library is used by git-http-fetch and git-fetch. You
might also want the "curl" executable for debugging purposes.
If you do not use http:// or https:// repositories, you do not
have to have them (use NO_CURL).

逆に言うと，httpやhttpsを使う時は，libcurlが必要っぽい．なので，curlを入れてから，そのcurlのlibcurlをリンクしたgitを作ることにします．

> wget http://curl.haxx.se/download/curl-7.21.7.tar.bz2
> tar xvf curl-7.21.7.tar.bz2
> cd curl-7.21.7
> ./configure --prefix=/usr/local

おっと．．．環境変数が伝搬していないのか．．．では改めて

> setenv CPPFLAGS -I/usr/local/include
> setenv LDFLAGS -L/usr/local/lib

> make -j 2

# make install
# exit

OK!!!
ちなみに，環境変数https_proxyの設定を忘れると次のようになります．

> git clone https://github.com/imatix/zguide.git
Cloning into zguide...
error: Couldn't resolve proxy 'proxy' while accessing https://github.com/imatix/zguide.git/info/refs

fatal: HTTP request failed

あり？SSL証明書関係のエラーが．なんでマシンによって挙動が変わるんだろう．仕方がないので，

> setenv GIT_SSL_NO_VERIFY true
> git clone https://github.com/imatix/zguide.git

OK!!!!!
CURLOPT_SSL_VERIFYPEERとかでもできそうな気がするのですが，何パターンか試してうまくいかなかったので諦めました．
