Well, I do not know what you are trying to achieve.

Usually, the transformation reads:
guix build foobar --with-source=foobar=/path/to/foobar/v9.5.0
or
guix build barbaz --with-inputs=foobar=foobar@9.5.0
The transformation ’with-source’ overwrites the origin of the target
package. Target package means the one specified after ’--with-source=’.
If you have 2 packages ’foobar’, one at version 9.0.1 and one at 9.5.0,
and you want to overwrite the source of 9.5.0, from my understanding,
you should write:
guix build foobar@9.5.0 --with-source=foobar@9.5.0=/path/to/foobar/v9.5.0-modif
Does it not work?
The transformation ’with-inputs’ overwrites the inputs. The package
’barbaz’ depends on the package ’foobar’ at one specific version; in the
input lists, there is ("foobar" ,foobar-9.0.1) and here ,foobar-9.0.1
refers to a symbol defining a package at a specific version. This
symbol is probably just ’foobar’, but if all is named foobar, the
explanations are made harder. ;-)
If you have another version of foobar, you have probably another symbol,
say foobar-9.5.0. Then ’with-inputs=foobar=foobar@9.5.0’ replaces the
symbol listed as inputs of ’barbaz’ by the symbol referring to
“foobar@9.5.0“. In the example, somehow, the symbol ’foobar-9.0.1’ will
be replaced by the symbol ’foobar-9.5.1’.
Now, be careful with ("identifier" ,symbol). I do not remember if
’with-inputs’ uses ‘identifier’ or the “name” that ’symbol’ defines. I
guess it is “name”. I agree that it can appear confusing; a change in
core-updates should remove this confusing ’identifier’, I guess. :-)

Is this command-line not working
guix build barbaz --with-source=foobar=/path/to/replaced/foobar
? Assuming the package ’barbaz’ depends on the package “foobar”.
Otherwise, maybe you can provide an concrete example defining the
package ’barbazz’ and ’foobar’. :-)
Cheers,
simon
