OK, this is done.

I seem to have some trouble with that.  The package passes all phases
except for "install".  When it reaches install I get the following
error:

---8<--- cut here -------------------- start --->8---
      Start 40: gtest_xml_outfiles_test

100% tests passed, 0 tests failed out of 41

Total Test time (real) =   4.68 sec
phase `check' succeeded after 6.7 seconds

The patch that created this error is attached.  I am not sure what is
happening here.  Is all of the code in the argument of modify phases
executed in a different scope where "version" is something else?  I do
not quite understand this.

>   (zero? (system* "cp" "libgtest.a" "libgtest_main.a"
> won't this just copy libgtest.a to libgtest_main.a ?

I am not sure, but if it behaves like invoking "cp" on the command line,
then it should copy both of these to the directory that is on the next
line:
+                         (zero? (system* "cp" "libgtest.a" "libgtest_main.a"
+                                         (string-append out "/lib"))))))))))

I replaced all these statements with (install-file ...) and
(copy-recursively ...) as mentioned by Leo.

Thank you for your help!

Best,
Lukas
