Description
Created attachment 259679 configure.ac with better umfpack linking.
If you build suitesparse from source or install it in Archlinux, only satic library are provides.
GEGL needs to link to these static libs (and not to shared one available in some distrso).
In attachment is a patch that changes configure.ac accordingly.
Please test.
