Bugzilla Bug 168041

The ebuild contains

built_with_use dev-scheme/guile regex || die "dev-scheme/guile must be built
with regex"
built_with_use dev-scheme/guile deprecated || die "dev-scheme/guile must be
built with deprecated"
built_with_use dev-scheme/guile discouraged || die "dev-scheme/guile must be
built with discouraged"

This means you try to emerge gnucash, get the failure and add the regex flag
for guile, emerge again and get another failure, add another USE flag, then
fail once again. The result is that you rebuild guile up to three times,
instead of once.

It would be better if each line contained

die "dev-scheme/guile must be built with the regex, deprecated and discouraged
USE flags."

It would be even better to die just once:

built_with_use dev-scheme/guile regex deprecated discouraged || die "..."

Fixed.

You've produced a bunch of typos there, making the ebuild die due to
non-existant flag.

-if !built_with_use dev-scheme/guile regex depricated discouraged; then
-die "dev-scheme/guile must be built with USE=\"regex depricated discouraged\""
+if ! built_with_use dev-scheme/guile regex deprecated discouraged; then
+die "dev-scheme/guile must be built with USE=\"regex deprecated discouraged\""

I swear I installed it before I committed...

Anyway, fixed again.
