Interestingly,

  guix build guile-gcrypt --with-commit=guile-gcrypt=v0.2.0

would work just fine.

This is because the tags in the above examples actually point to a
“commit” object instead of pointing to a “tag” object as in the
guile-gcrypt case.  Weird.

Fixed with commit efa578ecaece67366b4b0e2266de7c2faaa4ae54.

Thanks,
Ludo’.

Hello,

`--with-commit' from `guix build' doesn't always work. It seems to not
really update the checkout contrary to what is reported since changing 
the
`git-url`, by adding a slash for example, put it back on track. It makes 
it
useless when trying out to build a newly released version. Following are
some examples:

$ guix build mlt
/gnu/store/m6y21nnyg6p0kcxbfj7k1dnbwbsbj006-mlt-6.18.0
$ guix build mlt --with-commit=mlt=v6.18.0
updating checkout of 'https://github.com/mltframework/mlt.git'...
guix build: error: Git failure while fetching 
https://github.com/mltframework/mlt.git: the requested type does not 
match the type in the ODB
$ guix build mlt --with-commit=mlt=v6.18.0 
--with-git-url=mlt=https://github.com/mltframework/mlt.git/
updating checkout of 'https://github.com/mltframework/mlt.git/'...

I've found out about this issue by reading pelzflorian's suggestion 
about
adding a `--with-version' in [0] and [1], he wrote that a year ago, 
before
support for tags was added to `--with-commit'.
