Hello! I had determined here https://lists.gnu.org/archive/html/help-guix/2019-02/msg00275.html   that qtwebkit is necessary for openshot that I use. Qtwebkit takes much time, over 10 hours, compiling almost every time I run `guix pull && guix package -u`, every week I do it. Is there any way to solve this problem with wasting time? May be I can use openshot without qtwebkit? Or may be I can update packages without updating qtwebkit? Or may be guix.info will compile qtwebkit after dependencies update more pronto?
