Chief selector Omar Henry says South Africa's controversial quota system cannot be used as an excuse for a dismal World Cup performance.
Langeveldt's selection was particularly controversial
Prior to the tournament, the county's cricket board made a commitment to selecting five "players of colour" in the 15-man World Cup squad.
And, as BBC Sport exclusively revealed last month, there was a further "understanding" to field three of those players in matches against minnows Kenya, Bangladesh and Canada.
"Cricketers, both black and white, must accept this as part of today's set-up," Henry told South African national newspaper Business Day.
"We have a legacy that we have to correct, and we have to learn to function successfully within that context."
Batsman Herschelle Gibbs, all-rounder Robin Peterson and pace bowlers Makhaya Ntini, Charl
Langeveldt and Monde Zondeki were the five selected.
The selection of Langeveldt caused most uproar as he had not appeared for the national side in the year prior to the tournament.
He played a single match, taking nought for 24 in five overs against Kenya in a move criticised for preventing veteran pace man Allan Donald a chance to return to form.

"What [Langeveldt] does with what he has learned is up to him," said Henry - the first non-white player to represent South Africa.
"He can take negatives or he can take positives out of the experience and this will define his future.
"In 1992, I never played but what I learned about myself and what it took to be an international cricketer proved invaluable to me in the long run."
Gibbs and Ntini were two of the team's success stories in South Africa's otherwise dismal World Cup campaign which ended at the first round stage.
Gibbs hit 384 runs with a best of 143 and average of 96 while Ntini claimed 10 wickets at 17.60.
