Specifying custom location for package pari/gp when compiling sage

edit

Hi there,

When running ./configure to compile sage, it looks for a system install pari/gp in standard system location ( Debian ). I would like to know if there is a way to specify custom location for libpari and for the gp executable. Let say for example I have all pari/gp stuffs ( lib, include, binaries ... ) in the folder /home/myowncompiledpari. I would like to tell sage to use this files and not compile his own version. I tried to write a .pc file specifying locations, but it does not work. I also tried to look into the configure script to see how it look for it, but couldn't find my way out.

Thank you for your help John
