Wow, the UI is simple to use and seems powerful. New "window" spawning
inside on new clicks is also a nice feature , so switching between packages
is as easy as it can be. If this is the kind of UI mentioned in the ideas'
page, it seems to do the trick. Simple + Powerful.

I went through that thread and i guess the feature can be worked upon later
(not a point of concern in the nascent stage), so it would be better to
just focus on the core stuff for now.

Yes , i solved that, and another error related to an undefined reference to
sqlite3_exec, simply by configuring it with

 $ ./configure PKG_CONFIG=true GUILE_CFLAGS="" GUILE_LIBS=""
SQLITE3_LIBS="-lsqlite3"

I have a guix system up and running now, and guix-package install gcc seems
to have finished without errors.
I'll just check that.

Just two things that i noticed while installing GCC,
There's no resume support for partial downloads.
The progress bar should be confined to a single line rather than spanning
100*10 lines (one for each 0.1%) (at least that's what happened on my end ,
maybe i have a slow internet connection.)
Are these issues worth addressing as of now?

PS - Should i submit an application regarding Guix as GSOC Project now ?
