Thanks, Petronny. I've added that to the 7.34.2 PKGBUILD.

The previous error also occurs in 7.34.2 and it can be fixed by inserting export CFLAGS="${CFLAGS} -lm" before calling cmake.

Build failed.

@ejno, it's now fixed upstream in the git version as my fix got merged, so next release you can take the patch out :)

@ejno thanks. I use a proxy solved the problem. (you know the gfw)

@ljj038: If you're behind a proxy, try this: https://subversion.apache.org/faq.html#proxy
