This may be a little bit off topic for this list, since it is not an
issue with your package, but I'll try to answer anyway.

The header file /usr/include/curl/curl.h is provided by both the 32-bit
and 64-bit versions of libcurl-devel. I can reproduce your error if I
have libcurl-devel.i686 installed (which provides the header) but not
libcurl-devel.x86_64 (which is needed to compile the 64-bit version of
R). This gives me the following output:

checking for curl-config... /usr/bin/curl-config
checking libcurl version ... 7.37.0
Package libcurl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcurl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libcurl' found
checking curl/curl.h usability... no
checking curl/curl.h presence... no
checking for curl/curl.h... no
configure: error: libcurl >= 7.28.0 library and headers are required
with support for https
