Everything identical, but curl 7.x works perfectly fine:

checking for curl-config... /opt/local/bin/curl-config
checking libcurl version ... 7.88.1
checking for curl/curl.h... yes
checking if libcurl is version 7 and >= 7.28.0... yes
checking if libcurl supports https... yes

Ok, same error on 10.6.8 x86_64 with Xcode 4.2:

[jmroot (Joshua Root)]

The problem is pretty clearly

#if LIBCURL_VERSION_MAJOR > 7
|   exit(1);

Replying to jmroot:

The problem is pretty clearly

#if LIBCURL_VERSION_MAJOR > 7
|   exit(1);

Oh, indeed. What should we do? Just patch this out?

[ryandesign (Ryan Carsten Schmidt)]

Use the relevant portion of the patch​ that the developers already committed to their repository to fix this. If the port uses auto(re)conf, the relevant portion is the patch to the m4 file. If it doesn't, then it's the patch to the configure file.
