To install Shotwell in OSX

I install the first dependencies of Shotwell successfully

brew install libGphoto2 vala libgee 

The installation of exiv2 pyexiv2 should install gexiv2, according to this thread. However, I installed the commands successfully.

I run ./configure and get

Detected libGPhoto 2.5.x - using 2.5-aware code path.
Configured.  Type 'make' to build, 'make install' to install.

I run make and get

Package gexiv2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gexiv2.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gexiv2' found
...

My .bash_profile

if [ -f ~/.bashrc ]; then
    source ~/.bashrc
fi

# http://ift.tt/1CGxEiW
export PATH=/usr/bin:/usr/local/bin:/opt/local/sbin:$PATH

Echoing $PATH

/usr/bin:/usr/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/git/bin:/usr/texbin
