Hello Guix! I am trying packaging for first time :-) I made the package definition for GNU Gnash (gnash.scm), which I have attached with this email. I did `guix package --install-from-file=gnash.scm`, and ended up with some errors which I am not able to understand. I have attached the build log (gnash.drv) with this email. Could anyone please help me understand those errors and guide me how to proceed further? Thank you! Regards, RG.
