Because there are a lot of libraries not on the standard Mac, there is some preparation necessary. First of all you need the QT library . Compile and install it. The dynamic library must be also copied into the /usr/lib directory.
Next you need the packages for gif, jpeg, png tiff zlib and exif.
Compile all, and put the libraries into a lib directory and all include files into an include directory.
Then download the regular Perico package. Unpack it, and compile it.
Finaly it makes the Perico application.
