Re: Package Installation takes a very long time - normal?

OK, so it has finished but unsuccessfully. The last lines of the output were
as follows but none of the packages were installed. To reach this point it
took about 50 mins (it started around 19:55 and finished at 20:43).

The following packages will be installed:
   r-caret 6.0-76 /gnu/store/dybi25l6wr14y3cxw6xazans9vlqjlji-r-caret-6.0-76
   r-ggplot2 2.2.1 /gnu/store/11jzzbgpg67v3yysiv6pyhi27f75dyh1-r-ggplot2-2.2.1
   r-rpart 4.1-11 /gnu/store/rrsr0q4q4n2wjfg26kyg4klk708f675f-r-rpart-4.1-11
   r-e1071 1.6-8 /gnu/store/1r4if4p10rnyj6q073yjir99mpriv1d0-r-e1071-1.6-8
   r-randomforest 4.6-12

   r-class 7.3-14 /gnu/store/bqx4c9r3pzmf12vlfy2hdw8hamk8z45n-r-class-7.3-14

I had previously installed successfully R and r-catools via Guix.

Ok, I see. And is there something I need to do to only install the pre-built
substitutes and not to install from source?
