It would seem that you are building random with profiling enabled:
4. Build random-1.0.1.1 by new by ghc/7.4.1/instUnregis
by
ghc --make Setup
./Setup configure --prefix=/home/mechvel/ghc/7.4.1/instUnregis/lib/ghc-7.4.1 -p
./Setup build -v
while your non-reg'ged build of ghc has no profiling libraries.
At least that is what this error says:
* Serge D. Mechveliani
System/Random.hs:97:8: Could not find module `Numeric' Perhaps you haven't installed the profiling libraries for package `base'? Use -v to see a list of the files searched for. scico:~/ghc/random/random-1.0.1.1> ------------------------------------------------------------
The easiest is to remove the "-p" flag, if you do not need profiling enabled. Gruss, Christian
