What are your samples sizes? If there are equal or nearly so, the t-test
is robust with regard to unequal variances.
On the other hand, you could just read the part of the output that reports
results for equal variances not assumed. You might also consider using
a nonparametric procedure such

essentially what you do is to be a bit more conservative in your degrees of
