Errors encountered in building guix from source.

[Fis Trivial]

I am currently running guix on top of Fedora 26. This is a mix of several
problems, and possibly contains bugs in guix, I am not sure if I have done
anything wrong. So I will try to describe them in order. If you believe I
should make separate threads or fill a bug report, just tell me to.


I tried to build guix from git repo according to this menu:
https://www.gnu.org/software/guix/manual/guix.html#Building-from-Git

* Do as the menu said
So I ran the following command in sequence:
$ guix environment guix --ad-hoc help2man git strace
$ ./bootstrap
$ ./configure --localstatedir=/var

The last configure command resulted in error, here is the last part from output:
--8<---------------cut here---------------start------------->8---
configure: checking for guile 2.2
configure: found guile 2.2
checking for guile-2.2... no
checking for guile2.2... no
checking for guile-2... no
checking for guile2... /usr/bin/guile2
configure: error: found development files for Guile 2.2, but /usr/bin/guile2 
has effective version 2.0
--8<---------------cut here---------------end--------------->8---

It seems configure script tried to use the guile provided by Fedora.


* Add --pure option to `guix environment`
Then I tried again the added --pure option to `guix environment`:
$ guix environment  guix --ad-hoc help2man git strace --pure

During the process, following questions were emitted by command-not-found
facility provided by Fedora:
--8<---------------cut here---------------start------------->8---
Install package 'cargo' to provide command 'cargo'? [N/y] n

Install package 'procps-ng' to provide command 'pidof'? [N/y] n

Install package 'cargo' to provide command 'cargo'? [N/y] n

Install package 'procps-ng' to provide command 'pidof'? [N/y] n
--8<---------------cut here---------------end--------------->8---
Even if I answer 'y', those packages won't be successfully installed by Fedora
since I already have them.

Aside from this, The bootstrap and configure ran successfully. But `make check`
failed, here is the last part of the output:
--8<---------------cut here---------------start------------->8---

If I ignore the failure and then try:
$ sudo ./pre-inst-env guix-daemon --build-users-group=guixbuild

I will be told that sudo command is not availabile.
Adding sudo as a dependency in environment will not work, due to this error:

* Platform
Fedora 26 x86_64

* Version
The version of guix I'm running:
guix (GNU Guix) d77f2bd81f20a312032d6a7357e4f6f52047bf9c

The version of guix I'm trying to build:
commit ede75282b86ee9cd3b9066c4ce7b00387878709b

* Summary
So, as a summary, I encountered the following errors:
1. configure failed if I don't add --pure option to `guix environment`.
2. If I add --pure option to `guix environment`:
   1. Fedora will ask me whether should it install some packages.
   2. `make check` failed
   3. sudo is missing.

Is there anything I did wrong? Or is it a bug in guix? If so, should I report
them in one or multiple bug reports?
