To install Shotwell in OSX

I install the first dependencies of Shotwell successfully

brew install libGphoto2 vala libgee 

Some discussion about this issue in this thread but the accepted answer is misleading, since it is about how to install pyexiv2, not gexiv2.

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

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
