FAQ

Why with easy.url I obtain an "old" url and not the last used?

.url gives the url that curb processed when it was initialized, to resolve, simply use the .last_effective_url method, [taf2]

How to compile curb in FreeBSD? [Tested under FreeBSD 7.1{DesktopBSD}]

Install libcurl /usr/ports/ftp/curl and ruby /usr/ports/lang/ruby18, then do 'gem i curb', you will receive an error message, at the end you will see:

"Gem files will remain installed in /thir/to/cd/"

then simply

cd /thir/to/cd/
rake install EXTCONF_OPTS='--with-curl-dir=/usr/local/'

Curl::Easy.new takes a long time to run. Curl::Easy.new invokes curl_easy_init, which intern calls openssl functions - if libcurl was built using openssl. On Mac OSX, I observed 0.1 second delays when calling curl_easy_init. If you don't use SSL and need performance on Mac, I recommend NOT building libcurl with SSL support enabled.

Solution

sudo port install curl +universal

If the above doesn't output something like: (notice the x86_64) (if you see ppc) something is wrong!
