Here is the output of "guix package -i libxslt" (where apparently only the
profile needs to be built, as the package itself has been downloaded from

The following package will be installed:
   libxslt-1.1.28       out     /gnu/store/chrlyizhxf9djqhmd4cdy425plijah10-libxslt-1.1.28

The following derivation will be built:
   /gnu/store/hdhppd3jfbpbq53afmmh0p51lx259w8a-profile.drv
