 Hi, thanks for the report!

 Unfortunately I'm not able to reproduce your error.
 I successfully build gdb with python option on a amd64 10.0-ALPHA2 and I
 had no further problem.
 I've also tried on redports using different configurations, it was
 always OK.
 Are you using some special python configuration or make.conf?
 The patch you're proposing is a workaround, but not a solution. I prefer
 to find the error and solve it.

 Could you try the gdb-7.6.1? (PR ports/181801, still open, but in
 testing) It solves also an installation issue (some installed file was
 not plisted)

 Best regards,
 Luca
