chicken-install bug

[siiky]

Hi all,


I reported a chicken-install bug on IRC but figured it would be best to 
send an email in case people have missed it there.

The bug is that chicken-install fails to install/update an egg because 
of an error thrown by `make-pathname`.

I first encountered it trying to upgrade all my installed eggs. In 
particular, it failed trying to install sql-null. The root cause seems 
to be the `version` field of the egg file, which is a number instead of 
a string. Not sure it could make a difference, but I'm using the 
all-eggs repo.

In this paste[0] you'll find the error, possibly problematic egg files 
(i.e., files  with a non-string `version` field), and two possible 
patches (one of which I send attached). Two of the egg files result in 
an "unterminated list" error (math:0.2.2 & message-digest-utils:4.2.2), 
but they're not the latest version so not problematic anymore.

The reason for the two patches is that I found 3 possible "bad uses" of 
`make-pathname`, but one of them alone fixes the original problem. Maybe 
chicken-install can fail in other scenarios, I just couldn't understand 
in which...
