Troubles with Python versions in libopensync-unstable [SOLVED]

When I try to compile it with a PKGBUILD that is different from the one on the AUR only in that the package now shows to depend on python2, it tries to use the Python 2.5 library (/usr/lib/libpython2.5.so) even though I have Python 2.7.1. This causes the build process to fail, though it seems to happen when it recieves a traceback stating a SyntaxError in a print statement. It uses CMake, and I cannot figure out for the life of me where the Python .so is specified.
How do I force CMake (or rather, the FindPythonLibs module) to use the correct Python .so?

Re: Troubles with Python versions in libopensync-unstable [SOLVED]

Why don't you post up both of them here?

And why not use the one from the AUR?

Ok, here goes:
Original, from AUR:

# Maintainer: Konstantinos Karantias <kostis[at]gtklocker[dot]com>

build() {
  cd $srcdir/
  mkdir build
  cd build
  cmake ../libopensync-$pkgver -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release
  
  make VERBOSE=1
}

package() {
  cd $srcdir/build
  make DESTDIR=$pkgdir install
}

My modified version:

  rm -r build || true
  mkdir build
  cd build

  make VERBOSE=1
}

package() {
  cd $srcdir/build
  make DESTDIR=$pkgdir install
}

And a unified diff:

The makedepends modification was made because this library was trying to use python 2, not python 3. The other addition was to stop the immediately-following mkdir from pooping out because the directory already exists.

Re: Troubles with Python versions in libopensync-unstable [SOLVED]

You see, makedepends() does not affect compilation at all, its like a flag for pacman to know what MUST be installed before trying to build the package. So something else is the difference, not your PKGBUILD. Try removing your ./src directory before makepkg.

Re: Troubles with Python versions in libopensync-unstable [SOLVED]

Well, it turns out the only reason I even had the Python 2.5 library was because I had the Google App Engine SDK installed, so I did a

sudo pacman -Rc python25

and everything works fine now.
