I tried to build boinc for Android but it didn't work.

I used the instructions from
https://boinc.berkeley.edu/trac/wiki/AndroidBuildClient

but I get this error on build_boinc_arm.sh:

checking for the version of libcurl... 7.35.0
checking for libcurl >= version 7.17.1... yes
checking whether libcurl is usable... no
configure: error:
================================================================================
ERROR: could not find (recent enough) development-libs for libcurl.

This library is required to build the boinc-client.
(If you don't want to build the client, use --disable-client with configure.

If libcurl-dev is installed on your system, make sure that the script
'curl-config' is found in your PATH, and that
'curl-config --version' gives something recent enough (see above).

You can download libcurl from: http://curl.haxx.se/

Maybe you can say me what I am doing wrong
